CVE-2014-0502 — Adobe Flash Player Double Free Vulnerablity

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

CISA SSVC assessment CISA

Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

• Documented patch — helpx.adobe.com (NIST National Vulnerability Database)

CISA required action CISA

The impacted product is end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue utilization of the product.

US federal deadline: Oct 8, 2024 — passed 737 day(s) ago

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

1. Identify exposed assets running the affected vendor/product/version combinations (Adobe Air, Adobe Air Sdk, Adobe Flash Player…).
2. Treat as emergency remediation: the CVE is in CISA KEV (confirmed exploitation).
3. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
4. Apply the fixed version or the patch documented under Remediation.
5. Exploitation requires user interaction: tighten email/web filtering and warn affected users.
6. EPSS ahead of 98% of scored CVEs: prioritize it in the patch queue.
7. Search available logs for exploit probes matching the vulnerability class (memory corruption), errors and authentication anomalies.

CISA KEV details CISA

CISA lists a CVE once it has evidence of exploitation against real targets.

CISA records ransomware use only for campaigns it has confirmed, so “Unknown” means unrecorded, not ruled out. The deadline binds US federal agencies; for everyone else it is a reference date.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

• Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
• Correlate service crashes/restarts with inbound traffic; repeated crashes may indicate attempts.
• Hunt retroactively in logs from before Sep 17, 2024 (KEV listing): exploitation may have started earlier.
