CVSS v3.1 |
| The Custom Menu Wizard Widget WordPress plugin through 3.3.1 does not sanitize and escape several shortcode attributes before rendering them into HTML, allowing users with contributor-level access and above to inject arbitrary web scripts that execute when the affected content is viewed. |
| The Frontegg SAML SSO WordPress plugin through 1.0.1 does not verify the signature or issuer of SAML authentication responses before establishing a session, allowing unauthenticated attackers to log in as any user, including administrators, as well as to create arbitrary accounts. |
| The Temporary Login Without Password WordPress plugin before 1.9.9 does not verify that the user requesting a temporary login holds network super admin rights before granting the new account those rights, allowing an administrator of a single site on a multisite network to take over the whole network. The same missing check also allows an existing account, including the attacker's own, to be promoted. |
| The Temporary Login Without Password WordPress plugin before 1.9.9 does not prevent a temporary user from creating an Application Password, and does not revoke one when the temporary access expires or is disabled, allowing the recipient of a temporary login to retain working access to the site over REST and XML-RPC after the administrator believes it has been withdrawn. The retained access carries whatever role was granted, which for the Temporary Login Without Password WordPress plugin before 1.9.9's main use case is Administrator. |
| The SureRank SEO WordPress plugin before 1.10.1 does not exclude users' registered account email addresses from the structured data it outputs on public pages by default, allowing unauthenticated visitors to obtain the email address of any user who has published content. |
| The Gpx2Graphics WordPress plugin through 0.3 does not perform a CSRF check when handling file uploads, nor validate the type of the uploaded file, allowing attackers to make a logged-in administrator upload arbitrary files such as PHP via a CSRF attack, leading to Remote Code Execution. |
| The BE REST Endpoints WordPress plugin through 1.0.0 does not perform any authorization check before allowing widgets to be read, created, updated and deleted, and does not sanitize the values it stores in them, allowing unauthenticated users to inject arbitrary web scripts which will execute in the browser of any user visiting the site. |
| The BEAR WordPress plugin before 1.2.2 does not verify a CSRF nonce before saving its meta field configuration, allowing an attacker to overwrite that configuration by tricking a logged-in administrator into visiting a crafted page. |
| The WP images upload on piclect WordPress plugin through 1.0 does not validate the name or type of uploaded files before writing them to a publicly accessible directory, allowing unauthenticated attackers to upload arbitrary files and execute arbitrary code on the server. |
| The WP Highlight Box WordPress plugin through 1.0 does not escape some shortcode attributes before outputting them in a page where the shortcode is embedded, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks. |
| The Zonify WordPress plugin before 1.0.5 does not perform any capability or authentication check before returning the site's stored account login token, allowing unauthenticated attackers to retrieve it and authenticate to the site owner's linked service account. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: reject out-of-range useconds in NFSv2 SETATTR/CREATE
The NFSv2 sattr decoder converts the wire useconds to nanoseconds in
svcxdr_decode_sattr():
iap->ia_atime.tv_nsec = tmp2 * NSEC_PER_USEC;
tmp2 is a u32 and NSEC_PER_USEC is 1000, so the product is computed in
unsigned long. On ILP32 that is 32 bits, and an out-of-range useconds
value such as 4294968 wraps to tv_nsec == 704. The corruption therefore
happens during decode, before any proc function can inspect the value,
and a later range check on tv_nsec would see an in-range result and
accept it. Rejecting in the decoder yields an RPC GARBAGE_ARGS reply.
NFSv2 defines no NFSERR_INVAL, so there is no NFS-level status to return
for a malformed time argument, and the check cannot move to the proc
function the way the v3/v4 nsec range checks do.
Guard the raw useconds before the multiplication and reject values
greater than 1000000. useconds == 1000000 is kept: it is the Sun
convention for "set to the current server time", and the in-tree Linux
NFSv2 client emits it in both the atime and the mtime field for a plain
touch / utimes(file, NULL) (see encode_sattr() and
xdr_encode_current_server_time() in fs/nfs/nfs2xdr.c). Rejecting 1000000
would turn that common operation into a hard decode failure for both
SETATTR and CREATE. 1000000 * NSEC_PER_USEC is 10^9, which does not wrap
on ILP32, so the Sun convention value passes through safely. Only
genuinely out-of-range values (> 1000000) are rejected. The atime and
mtime guards are therefore symmetric.
The decoder only applied the Sun convention in the mtime block, which
clears ATTR_ATIME_SET|ATTR_MTIME_SET when mtime useconds == 1000000. If a
client puts 1000000 in the atime field but not in the mtime field, the
atime block stored an out-of-range tv_nsec (10^9) and left ATTR_ATIME_SET
set, so the bogus value reached the filesystem. Apply the convention in
the atime block as well, clearing ATTR_ATIME_SET so the server uses its
current time and ignores the value. Only ATTR_ATIME_SET is cleared there.
The mtime block keeps its existing behavior, where 1000000 means "set
both atime and mtime to now".

| In the Linux kernel, the following vulnerability has been resolved:
nfsd: reject out-of-range nseconds in NFSv3 SETATTR and create ops
A client can send an NFSv3 SETATTR, CREATE, MKDIR, SYMLINK or MKNOD
carrying an atime or mtime whose nseconds field is out of range. The
value is well-formed on the wire and decodes cleanly into a valid
uint32, but it is not a valid timespec64: tv_nsec must be less than
NSEC_PER_SEC.
Nothing in the setattr path clamps it. notify_change() runs the time
through timestamp_truncate(), which does not reduce tv_nsec below
NSEC_PER_SEC when the filesystem supports nanosecond granularity
(s_time_gran == 1), and the inode atime/mtime setters store it verbatim
(only ctime is normalized, via inode_set_ctime_to_ts()). The
un-normalized value then corrupts on-disk metadata: ext4's
ext4_encode_extra_time() shifts tv_nsec left by EXT4_EPOCH_BITS, which
overflows the 32-bit extra field and clobbers the seconds-epoch bits, so
the stored seconds (and thus the year) are wrong on read-back. XFS with
bigtime mis-stores the timestamp for the same reason.
Validate the client-supplied atime/mtime in the proc handlers and return
NFS3ERR_INVAL before anything is changed. RFC 1813 lists NFS3ERR_INVAL
for SETATTR and describes it as the error for a value the server 'can
not store ... in its own representation'; the client maps it to EINVAL.
Checking in the proc handlers, rather than in nfsd_setattr(), keeps the
rejection in front of object creation. The create operations create the
object before nfsd_create_setattr() runs, so a late failure would leave
the new object behind and turn a non-idempotent request into a namespace
change that reports failure. The check is therefore done up front, for
the create operations before the object is created.
tv_nsec is a long, so the comparison casts it to unsigned long (the same
width) rather than to u32, matching timespec64_valid(). A u32 cast would
truncate on 64-bit; the unsigned long cast also rejects a value that
became negative when an out-of-range u32 wire nseconds was assigned to a
32-bit long.
Only client-supplied times are checked: SET_TO_SERVER_TIME requests
carry no client value. The sattrguard3 ctime is deliberately left alone:
an out-of-range guard simply never matches the object's ctime and yields
NFS3ERR_NOT_SYNC via the existing guardtime comparison, which is the
protocol-correct outcome rather than rejecting the request. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: gate nfs2 setacl by argp->mask
The NFSACL v2 SETACL path shares the decoder convention used by its
v3 sibling: nfsaclsvc_decode_setaclargs() fills in argp->acl_access
only when NFS_ACL is set in the request mask and argp->acl_default
only when NFS_DFACL is set, leaving the other pointer NULL because
the argument buffer is zeroed up to pc_argzero before decode.
nfsacld_proc_setacl() then hands both pointers to set_posix_acl()
unconditionally. set_posix_acl(idmap, dentry, type, NULL) is the VFS
"remove this ACL type" operation, so an omitted arm is
indistinguishable from an explicit request to delete that ACL. A
SETACL carrying only NFS_ACL silently strips the directory's default
ACL; mask=0 strips both.
This is the same defect just fixed in nfsd3_proc_setacl(); apply the
same remedy. Gate each set_posix_acl() call on its mask bit and
initialize error to 0 so that a request with neither bit set leaves
the on-disk ACLs untouched and returns success. The out_drop_lock
path and the unconditional posix_acl_release() in
nfsaclsvc_release_setacl() already tolerate the skipped arms. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix possible fh_compose of wrong dentry in nfsd4_create_file()
dentry_create() can hypothetically provide a different dentry than the
one passed in. This could happen, for example, if the exported
filesystem is NFS, and the server returned to OPEN a filehandle which
matched a directory that was already in the dcache. Clearly this would
not be expected!
If this were to happen the dentry (child) that was already stored in
resfhp could be freed and later dereferenced.
We shouldn't call fh_compose() until we are certain that we have the
final dentry, so this patch moved the fh_compose() call to two places:
one for the case where the target already exists, and one after
dentry_create() where it was created. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: gadget: Fix use-after-free in dwc3_gadget_free_endpoints due to race condition
In dwc3_gadget_init_endpoint, &dep->nostream_work is bound with
dwc3_nostream_work, and dwc3_gadget_endpoint_stream_event can queue
this delayed work on system_percpu_wq when a DEPEVT_STREAM_NOSTREAM
event is received.
If we remove the gadget, dwc3_gadget_free_endpoints makes cleanup and
the memory allocated for dep with kzalloc() is released by kfree(dep),
while the delayed work mentioned above may still be pending or
running. The sequence of operations that may lead to a UAF bug is as
follows:
CPU0 CPU1
| dwc3_thread_interrupt
| dwc3_endpoint_interrupt
| dwc3_gadget_endpoint_stream_event
| queue_delayed_work(system_percpu_wq,
| &dep->nostream_work)
dwc3_gadget_free_endpoints |
dwc3_free_trb_pool(dep) |
list_del(&dep->endpoint.ep_list) |
dwc3_debugfs_remove_endpoint_dir(dep) |
kfree(dep) |
// dep is freed |
| dwc3_nostream_work
| // use dep (use-after-free)
Fix it by canceling the delayed work before kfree(dep) in
dwc3_gadget_free_endpoints. |
| In the Linux kernel, the following vulnerability has been resolved:
Revert "media: v4l2-dev: fix error handling in __video_register_device()"
This reverts commit 2a934fdb01db6458288fc9386d3d8ceba6dd551a.
The intentions of that patch were good, but it doesn't work.
The idea is that if device_register fails, you have to do a put_device
to let the ref counter release resources.
However, the V4L2 API says that if video_register_device() fails, then
you have to call video_device_release(), which kfree()s the video_device
struct.
But the put_device() will already have freed the struct, so you end
up in a double-free scenario.
There is not really a good way of fixing this without breaking
video_register_device() into two parts, one that initializes everything,
and one that does the actual device_register, and then converting all
V4L2 drivers to this new model.
That is a massive job, and it is very unlikely that device_register
will fail.
So rather than ending up in a double-free scenario, just revert this
patch, and in that case we'll have a small memory leak. Which is a lot
more robust. |
| An issue was discovered in OpenStack Keystone before 29.0.3. Tokens obtained via delegated authentication methods (EC2 credentials, application credentials, OAuth1 access tokens, and trusts) are not blocked from creating, modifying, or deleting credentials via the /v3/credentials API. EC2-derived tokens can additionally read credential blobs, exposing TOTP MFA seeds and other secrets. Also, PATCH /v3/credentials does not validate the requested post-update project_id, allowing any delegated token to move a credential to an unauthorized project. All Keystone deployments using delegated authentication are affected. |
| A web interface reflects a portion of the request URL into a script context and a hyperlink attribute without adequate encoding, and does not require authentication to reach. This allows an unauthenticated network attacker to craft a link that, when visited by a user, executes arbitrary script in the context of the affected application and can redirect the user's browser to an arbitrary external site. Successful exploitation could allow an attacker to act with the compromised user's session privileges within the application. |
| An interface that accepts file uploads from authenticated users extracts the contents of uploaded archives without validating that extracted file paths remain within the intended destination directory. This allows an authenticated attacker to craft an archive whose entries traverse outside the destination directory, causing the extraction process to write files to arbitrary locations with the privileges of that process. This could allow an attacker to inject fabricated records into the system's stored data or tamper with application configuration. |
