CVSSv4.0: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red]

CVE-ID: CVE-2025-1094

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in the database.

The vulnerability exists due to insufficient validation of quoting syntax in PostgreSQL libpq functions PQescapeLiteral(), PQescapeIdentifier(), PQescapeString(), and PQescapeStringConn() and within the command line utility programs when client_encoding is BIG5 and server_encoding is one of EUC_TW or MULE_INTERNAL. A remote attacker can pass specially crafted input to the application and execute arbitrary SQL queries in the database.

Note, the vulnerability is being actively exploited in the wild.

Mitigation

Install updates from vendor's repository.

EUVDB-ID: #VU76042

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-2455

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to incomplete fix for #VU40402 (CVE-2016-2193) that did not anticipate a scenario involving function inlining. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications.

This affects only databases that have used CREATE POLICY to define a row security policy.

Mitigation

Install updates from vendor's repository.

14) Security Features

EUVDB-ID: #VU40402

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2016-2193

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to manipulate data.

PostgreSQL before 9.5.x before 9.5.2 does not properly maintain row-security status in cached plans, which might allow attackers to bypass intended access restrictions by leveraging a session that performs queries as more than one role.

Mitigation

Install updates from vendor's repository.
