Critical SQL Injection Vulnerability Discovered in Piwigo 13.6.0 (CVE Pending)

Critical SQL Injection Flaw Identified in Piwigo 13.6.0

Security researchers have disclosed a severe SQL injection vulnerability in Piwigo 13.6.0, a popular open-source photo gallery software. The flaw, tracked under Exploit-DB ID 52443, allows attackers to execute arbitrary SQL queries, potentially leading to unauthorized database access, data exfiltration, or complete system compromise.

Technical Details

The vulnerability resides in Piwigo’s core functionality, specifically in how the application processes user-supplied input. While the exact vector has not been publicly detailed to prevent immediate exploitation, SQL injection flaws typically arise from insufficient input validation or improper use of prepared statements. Attackers could exploit this weakness by crafting malicious SQL queries via manipulated HTTP requests, bypassing authentication mechanisms or extracting sensitive information directly from the database.

At the time of disclosure, no CVE ID has been assigned to this vulnerability. However, security teams are advised to monitor official Piwigo channels and the Exploit-DB entry for updates, including patch availability and mitigation guidance.

Impact Analysis

SQL injection vulnerabilities are among the most critical web application flaws, ranked #3 in the OWASP Top 10 for 2021. Successful exploitation of this Piwigo flaw could enable:

• Unauthorized data access: Extraction of user credentials, personal data, or gallery metadata.
• Privilege escalation: Bypassing authentication to gain administrative control.
• Database manipulation: Altering or deleting records, including photo metadata or user accounts.
• Remote code execution (RCE): In worst-case scenarios, chaining this flaw with other vulnerabilities to execute arbitrary code on the server.

Given Piwigo’s widespread use in hosting personal and professional photo galleries, this vulnerability poses a significant risk to organizations and individuals relying on the software for image management.

Recommendations

1. Immediate Actions:

   • Monitor official sources: Track updates from Piwigo’s security advisories and the Exploit-DB entry for patches or workarounds.
   • Restrict access: Limit exposure by restricting Piwigo installations to trusted networks or behind Web Application Firewalls (WAFs) configured to block SQL injection attempts.
   • Disable vulnerable features: If possible, disable or restrict functionality tied to the vulnerable component until a patch is available.

2. Long-Term Mitigations:

   • Input validation: Ensure all user-supplied input is rigorously validated and sanitized.
   • Prepared statements: Use parameterized queries to prevent SQL injection in custom code or plugins.
   • Regular audits: Conduct security audits and penetration testing to identify and remediate similar vulnerabilities.

3. For Developers:

   • Review the Exploit-DB proof-of-concept (PoC) once published to understand the attack vector and implement fixes.
   • Contribute to the Piwigo project by assisting with patch development or testing.

Security teams should treat this vulnerability as a high-priority issue and allocate resources to mitigate risks until an official patch is released.
