EXPLOIT

FileRun (version 2017.09.18 and below) suffers from a remote SQL injection vulnerability due to a failure to sanitize input in the metafield parameter inside the metasearch module (under the search function).

• → Detect time-based blind SQLi exploitation attempts targeting the `metafield` POST parameter in FileRun's metasearch module. Look for HTTP POST requests containing `searchType=meta` combined with SQL sleep/delay payloads in the `metafield` parameter. ↗
• → Monitor for POST requests with `searchType=meta` and `searchPath=/ROOT/HOME` alongside anomalous `metafield` values containing SQL syntax (parentheses, AND clauses, numeric comparisons), which are characteristic of the exploit's time-based enumeration loop. ↗
• → Alert on repeated sequential POST requests to the FileRun search endpoint with incrementing numeric patterns in `metafield`, consistent with the exploit's character-by-character database enumeration (outer loop m=1..255, inner loop n=32..126). ↗
• → Correlate HTTP response timing anomalies (responses meeting or exceeding a configured delay threshold) on the FileRun search endpoint as an indicator of successful time-based blind SQL injection. ↗

• · The exploit authenticates before injecting; detection based solely on unauthenticated traffic will miss this attack. Session/cookie-based correlation is required to attribute the SQLi to a specific authenticated user session. ↗
• · The vulnerability affects FileRun version 2017.09.18 and below. Ensure version fingerprinting is in scope when triaging alerts, as patched versions are not affected. ↗
