Lifecycle Timeline
1DescriptionCVE.org
Guardian language-system passes the id GET parameter directly into an unsanitized SQL query in job_info_get.php (line 16): SELECT * FROM jobs where input1 = '\".$_GET['id'].\"'. An authenticated attacker can perform error-based SQL injection to extract database contents.
AnalysisAI
SQL injection in Guardian language-system via the 'id' GET parameter in job_info_get.php lets attackers inject arbitrary SQL into a query against the 'jobs' table, enabling error-based extraction of database contents. The CVSS 4.0 vector (AV:N/PR:N) and VulnCheck advisory title indicate unauthenticated network exploitation, though the CVE description text describes an 'authenticated attacker' - a discrepancy defenders should verify. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The concrete prerequisite is network reachability of the job_info_get.php endpoint and the ability to supply the 'id' GET parameter, which is passed unsanitized into the jobs-table query. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals mostly align toward high priority: CVSS 4.0 base 9.3 (Critical) with AV:N, AC:L, AT:N, PR:N, UI:N and full VC/VI/VA:H, plus a publicly available PoC, means a network-reachable, low-complexity attack with no user interaction that fully compromises the database. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker locates an internet-exposed Guardian language-system instance and sends a GET request to job_info_get.php with a crafted id parameter containing a single quote and an error-based SQLi payload. The application's database error responses leak query results, letting the attacker iteratively dump table contents such as credentials or sensitive job data. … |
| Remediation | No vendor-released patch or fixed version is identified in the available data (No vendor-released patch identified at time of analysis), so the primary code fix is to replace the concatenated query in job_info_get.php with a parameterized/prepared statement (e.g., PDO or mysqli bound parameters) and to cast or validate the 'id' parameter to its expected type. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Guardian language-system instances and assess network exposure; implement Web Application Firewall (WAF) rules to block SQL injection patterns in the 'id' GET parameter. …
