DescriptionCVE.org

SPIP versions prior to 4.4.10 contain a SQL injection vulnerability that allows authenticated low-privilege users to execute arbitrary SQL queries by manipulating union-based injection techniques. Attackers can exploit this SQL injection flaw combined with PHP tag processing to achieve remote code execution on the server.

AnalysisAI

SQL injection in SPIP prior to 4.4.10 enables authenticated users with low privileges to execute arbitrary SQL commands and achieve remote code execution through union-based injection combined with PHP tag processing. The vulnerability affects SPIP and PHP environments, requiring only network access and valid credentials to exploit. No patch is currently available, presenting significant risk to production SPIP installations.

Technical ContextAI

Classified as CWE-89 (SQL Injection). Affects Spip. SPIP versions prior to 4.4.10 contain a SQL injection vulnerability that allows authenticated low-privilege users to execute arbitrary SQL queries by manipulating union-based injection techniques. Attackers can exploit this SQL injection flaw combined with PHP tag processing to achieve remote code execution on the server.

RemediationAI

Monitor vendor advisories for a patch. Use parameterized queries. Implement input validation. Restrict network access to the affected service where possible.
