Detect BerriAI LiteLLM SQL Injection Exploitation (CVE-2026-42208) in CrowdStrike LogScale
Detects exploitation attempts targeting a SQL injection vulnerability in BerriAI LiteLLM (CVE-2026-42208, CWE-89). LiteLLM is a widely deployed LLM proxy/gateway; successful exploitation allows unauthenticated or authenticated attackers to manipulate backend database queries, potentially exfiltrating API keys, user data, model configurations, and spend tracking records. This CVE is listed on the CISA KEV catalog, indicating active exploitation in the wild.

Testing Methodology
Validate this detection against 4 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Error-Based SQL Injection on LiteLLM /key/info Endpoint
Expected signal: HTTP 500 or 422 response from LiteLLM; database error message in application logs; WAF alert if deployed
- Test 2UNION SELECT Injection Attempt on /user/info Endpoint
Expected signal: HTTP 500 or data leak in response body; PostgreSQL logs show UNION SELECT statement; network proxy logs capture full URL with UNION payload
- Test 3Time-Based Blind SQL Injection via LiteLLM /spend/logs
Expected signal: Response time >= 5 seconds; PostgreSQL slow query log entry for pg_sleep; application logs show extended request duration
- Test 4POST Body SQL Injection to LiteLLM /key/generate
Expected signal: HTTP 400/500 with SQL error in response; application log shows malformed query; SIEM alert on POST body containing OR 1=1
