CVSS v3.1 |
| UltraVNC viewer through 1.8.2.2 contains an off-by-one stack buffer overflow in the RFB ServerInit message handler. In vncviewer/ClientConnection.cpp, when the server-supplied nameLength equals exactly 2024 the code declares a 2024-byte stack buffer _dn[2024] and calls ReadString(_dn, 2024). ReadString writes the NUL terminator at buf[length], i.e., _dn[2024], one byte past the end of the stack buffer. A malicious VNC server can trigger this condition by advertising a desktop name of length 2024 in its ServerInit message. On release builds without stack canaries the single-byte NUL overwrite adjacent stack data. On builds with /GS stack protection the canary is corrupted and the process terminates, resulting in denial of service. User interaction (connecting the viewer to the malicious server) is required. |
| UltraVNC through 1.8.2.2 uses inadequate cryptography in the MS-Logon II authentication scheme (rfbUltraVNC_MsLogonIIAuth). In rfb/dh.cpp the Diffie-Hellman key exchange is performed with parameters that fit in an unsigned 64-bit integer (DH_MAX_BITS controls the prime size). A 64-bit DH key can be broken by Pollard's rho algorithm in under one second on current hardware. Additionally, the private exponent is generated by the rng() function, which multiplies three libc rand() values seeded from time(NULL). With approximately 31 bits of internal state and a time-based seed, the private exponent is recoverable in under a minute by a passive observer. A network attacker who can observe the MS-Logon II handshake (via sniffing, recording, or man-in-the-middle) can derive the shared DH key and decrypt the encapsulated username and password, resulting in full credential disclosure. This affects legacy MS-Logon II connections; MS-Logon III (X25519 + AES-256-GCM) is unaffected. |
| UltraVNC repeater through 1.8.2.2 contains a post-authentication out-of-bounds write in the allow/deny rule parser. In repeater/webgui/settings.c:225-272, after strncpy_s copies a rule token into temp1[rule1] (25-byte destination) or temp2/temp3 (16-byte destination), the code unconditionally writes a NUL terminator at temp1[rule1][len] = 0 without clamping len to the destination size. When an authenticated administrator saves a rule with a token length equal to or greater than the destination size, the NUL byte is written one or more bytes past the end of the stack-allocated array, corrupting adjacent stack data. An attacker who has obtained admin credentials (including via CVE-2026-7839 default password) can trigger this to gain code execution on the repeater host. |
| UltraVNC repeater through 1.8.2.2 initializes the HTTP administration server with a hardcoded default password. In repeater/webgui/settings.c:197, when settings2.txt is absent on first run the repeater writes the literal string "adminadmi2" as the admin password via strcpy_s(saved_password, 64, "adminadmi2"). The HTTP Basic-auth handler wi_decode_auth() checks this password without rate-limiting or lockout. Any remote attacker who can reach the repeater HTTP port (default TCP 80) can authenticate as administrator using the well-known default credential on a fresh or unmodified installation, gaining full control of the repeater configuration including allow/deny rules and session visibility. |
| A compromised or malicious BOSH Director can execute arbitrary shell commands on the operator's workstation when the operator runs bosh ssh (or bosh scp/bosh logs -f) with default flags.
Affected versions: BOSH CLI versions prior to 7.10.5. |
| The public dashboard deletion endpoint does not enforce organization isolation, allowing an Org Admin in one organization to delete public dashboards belonging to a different organization by supplying the target dashboard's identifiers. |
| Improper authorization in the /tequilapi/config/user endpoint of Mysterium Node before v1.36.0 allows unauthenticated attackers to arbitrarily overwrite the node's configuration and achieve a full node takeover via supplying a crafted POST request. |
| In CAXperts UPVWebServices 2.4.2212.603 through 2.7.6 and UDiTH Portal 2026.0.0 through 2026.2.0, an authenticated remote user can invoke an administrative API endpoint intended for privileged users. Due to missing authorization checks, this allows the attacker to deactivate the application's license. |
| A SQL injection vulnerability in SOGo before 5.12.7 allows authenticated users to execute arbitrary SQL statements via the search parameter of the allContactSearch endpoint. |
| A SQL injection vulnerability in SOGo before 5.12.7 allows authenticated users to execute arbitrary SQL statements via the newPassword parameter in the password change functionality. |
| In OpENer 2.3.0 (commit 76b95cf), a resource exhaustion (Denial of Service) vulnerability exists in its network processing loop. |
| An issue in Code27 Companion Hub SQ3A.220705.003.A1 allows a physically proximate attacker to execute arbitrary code via the USB debugging (ADB) and Android Debug Bridge components |
| An issue in SQLite before Fossil check-in 869a51ae84df allows a local attacker to obtain sensitive information via the Session Extension changeset concat/changegroup merge path |
| Incorrect authorization in the XML-RPC API of WebPros Plesk before 18.0.78.4 allows a low-privileged authenticated customer to look up domains they do not own, because ownership is enforced only for certain lookup filters and schema validation is bypassed for legacy protocol versions. This results in cross-tenant disclosure of other tenants' FTP credentials stored in cleartext, which can be leveraged to execute code as another tenant's system user. |
| Use after free in Ozone in Google Chrome prior to 150.0.7871.115 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Critical) |
| Uninitialized Use in V8 in Google Chrome prior to 150.0.7871.115 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High) |
| Use after free in InterestGroups in Google Chrome prior to 150.0.7871.115 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High) |
| Use after free in Views in Google Chrome prior to 150.0.7871.115 allowed a remote attacker who convinced a user to engage in specific UI gestures to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High) |
| Use after free in Autofill in Google Chrome on Android prior to 150.0.7871.115 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High) |
