Guardian language-system passes the id GET parameter directly into an unsanitized SQL query in subtitles.php (line 16): SELECT id, filename, extension, type FROM files where id = '\".$_GET['id'].\"'. An authenticated attacker can perform error-based SQL injection to extract database contents.
AnalysisAI
SQL injection in Guardian Language-System's subtitles.php lets attackers extract arbitrary database contents by tampering with the id GET parameter, which is concatenated directly into a SELECT query without sanitization. The flaw is error-based and rated critical (CVSS 4.0 base 9.3, VC:H/VI:H/VA:H), publicly available exploit code exists (VulnCheck advisory plus a public gist PoC), and there is no public exploit identified as being used in active attacks. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The exploitable code path is the id GET parameter of subtitles.php, which is concatenated into the 'SELECT id, filename, extension, type FROM files where id = ...' query; reaching it requires network access to that specific script on a deployed Guardian language-system instance. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals point to a genuinely high priority for exposed instances but with one important caveat. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a request to subtitles.php with a crafted id parameter such as id=1' AND (SELECT ...)-- , breaking out of the quoted SQL string to inject a subquery whose result surfaces through a database error message (error-based extraction). Because a public PoC gist exists and the CVSS vector indicates network access with low complexity and no user interaction, the attacker iteratively dumps table and column contents - including credentials or other sensitive data - from the files database and beyond. |
| Remediation | No vendor-released patch identified at time of analysis, and no fixed version is provided in the input data, so the primary durable fix cannot yet be cited by version - monitor the VulnCheck advisory (https://www.vulncheck.com/advisories/guardian-language-system-unauthenticated-sql-injection-via-id-parameter-in-subtitles-php) for a patched release. … Detailed patch versions, workarounds, and compensating controls in full report. |
