Summary

CVE-2023-27112 is a critical-severity SQL Injection (CWE-89) vulnerability in A54552239 Pearprojectapi. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 44.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2023-27112 is a SQL injection vulnerability (CWE-89) affecting pearProjectApi version 2.8.10. The issue resides in the projectCode parameter within the project.php endpoint, allowing malicious SQL queries to be injected and executed against the backend database. Published on 2025-01-21, it carries a CVSS v3.1 base score of 9.8, indicating critical severity due to its network accessibility and high impact potential.

The vulnerability can be exploited by unauthenticated remote attackers over the network with low complexity and no user interaction required (AV:N/AC:L/PR:N/UI:N/S:U). Successful exploitation grants high confidentiality, integrity, and availability impacts (C:H/I:H/A:H), enabling attackers to extract sensitive data, modify database contents, execute arbitrary SQL commands, or disrupt service availability.

Mitigation details are available in the GitHub issue at https://github.com/a54552239/pearProjectApi/issues/32, which documents the discovery and may include patch information or workarounds for affected deployments.
