Full Report
A novel PostgreSQL flaw, CVE-2025-1094, has hit the headlines. Defenders recently revealed that attackers responsible for weaponizing a BeyondTrust zero-day RCE are also in charge of abusing another critical security issue in PostgreSQL. SOC Prime Platform for collective cyber defense helps organizations proactively detect vulnerability exploitation attempts using relevant context-enriched Sigma rules compatible with dozens of SIEM, […] The post CVE-2025-1094 Exploitation, a Critical SQL Injection Vulnerability in PostgreSQL That Can Lead to Arbitrary Code Execution appeared first on SOC Prime.
Analysis Summary
# Vulnerability: Critical SQL Injection in PostgreSQL Leading to Arbitrary Code Execution
## CVE Details
- CVE ID: CVE-2025-1094
- CVSS Score: Not explicitly provided, but described as **Critical**
- CWE: SQL Injection (Implicit, due to SQL injection resulting in shell command execution)
## Affected Systems
- Products: PostgreSQL
- Versions: Not explicitly listed, but fixed versions suggest all prior major versions were affected.
- Configurations: Related to PostgreSQL's handling of invalid UTF-8 characters.
## Vulnerability Description
CVE-2025-1094 is a critical SQL Injection vulnerability rooted in how PostgreSQL handles invalid UTF-8 characters. Threat actors can exploit this flaw by leveraging the `!` shortcut command (a meta-command) within the injection context. This allows them to abuse OS shell commands, potentially leading to Arbitrary Code Execution (ACE) on the underlying system, or the execution of arbitrary SQL statements.
## Exploitation
- Status: Implied to be **Exploited in the wild** or highly dangerous, as it was discussed alongside the remediation efforts for a previously known vulnerability (CVE-2024-12356).
- Complexity: Implied to be **Medium** to **Low** due to the direct path to RCE via a common mechanism (`!` meta-command).
- Attack Vector: **Network** (as it is an SQL Injection in a database product).
## Impact
- Confidentiality: High (Potential data exfiltration via SQL injection or compromised host)
- Integrity: High (Ability to execute arbitrary SQL/OS commands)
- Availability: High (Potential system compromise and shutdown)
## Remediation
### Patches
PostgreSQL maintainers addressed the issue in the following versions:
- PostgreSQL 17.3
- PostgreSQL 16.7
- PostgreSQL 15.11
- PostgreSQL 14.16
- PostgreSQL 13.19
### Workarounds
No specific workarounds are detailed in this summary, but securing the input handling related to UTF-8 or disabling the use of the `!` meta-command for certain roles might serve as temporary mitigations if patching is delayed.
## Detection
- Indicators of compromise: Unexpected execution of OS shell commands originating from PostgreSQL processes.
- Detection methods and tools: Utilizing detection engineering platforms (like SOC Prime's offerings) to look for patterns indicative of SQL injection payloads that utilize the `!` meta-command targeting shell execution.
