  1. CVE exploitation

    CVE-2024-21887 exploitation attempt

    Keys on the distinctive part of the exploit request only (path traversal, exploit syntax in the query, an unusual parameter) — never on an endpoint the product serves in normal use. Needs raw request-URI logging (some web servers normalise ../ away). Scanners hitting the internet produce true-positive ATTEMPTS: correlate with sc-status / response size before declaring compromise.

How to deploy

SIGSigma

  1. 1.Convert for your SIEM with sigma-cli / pySigma, e.g. sigma convert -t splunk -p sysmon rule.yml.
  2. 2.Run it as a hunt first: every rule ships as status experimental.
  3. 3.Promote to an alert once a week of results is clean on your data.

Check · The processing pipeline must map the logsource (firewall, dns, proxy, webserver, process_creation) to your field names.

AQLIBM QRadar

  1. 1.Create the reference set from its spec (Reference Data API, or Admin > Reference Set Management) and schedule the skopnix feed load.
  2. 2.Paste the AQL into Log Activity > Advanced Search to hunt the last seven days.
  3. 3.For alerting, build the CRE rule from the test stack shown and exclude your known-good building block.

Check · Custom properties ("URL Host", "URL", "File Hash", "Process CommandLine") come from your DSMs and content extensions; rename them if yours differ.

XQLCortex XDR

  1. 1.Paste the XQL into Incident Response > Investigation > Query Builder > XQL Search.
  2. 2.To alert, save it as a Correlation Rule and set the MITRE tactic and technique printed with the rule.
  3. 3.Schedule it on the interval you hunt at; keep the fields stage for the alert's columns.

Check · CVE rules read PAN-OS URL logs (panw_ngfw_url_raw), which need the NGFW integration and, for HTTPS, decryption.
