CVE-2013-0648 — Adobe Flash Player Code Execution Vulnerability

Unspecified vulnerability in the ExternalInterface ActionScript functionality in Adobe Flash Player before 10.3.183.67 and 11.x before 11.6.602.171 on Windows and Mac OS X, and before 10.3.183.67 and 11.x before 11.2.202.273 on Linux, allows remote attackers to execute arbitrary code via crafted SWF content, as exploited in the wild in February 2013.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

How the score was calculated
  • Confirmed exploitation (CISA KEV)+35
  • EPSS 11.1% (30-day exploitation probability)+14
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

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

Remediation

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

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 Flash Player, Opensuse Opensuse, Red Hat Enterprise Linux Desktop…).
  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 96% of scored CVEs: prioritize it in the patch queue.
  7. Search available logs for exploit probes, 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).
  • Hunt retroactively in logs from before Sep 17, 2024 (KEV listing): exploitation may have started earlier.
