CVE-2012-0767 — Adobe Flash Player Cross-Site Scripting (XSS) Vulnerability

Cross-site scripting (XSS) vulnerability in Adobe Flash Player before 10.3.183.15 and 11.x before 11.1.102.62 on Windows, Mac OS X, Linux, and Solaris; before 11.1.111.6 on Android 2.x and 3.x; and before 11.1.115.6 on Android 4.x allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, aka "Universal XSS (UXSS)," as exploited in the wild in February 2012.

Who exploits it and how urgent it is

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

CISA KEV · Jun 8, 2022
How the score was calculated
  • Confirmed exploitation (CISA KEV)+35
  • EPSS 6.2% (30-day exploitation probability)+14
  • Technical severity (medium)+3

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.

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).
  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 93% of scored CVEs: prioritize it in the patch queue.
  7. Search available logs for exploit probes matching the vulnerability class (cross-site scripting), errors and authentication anomalies.

CISA KEV details CISA

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

Listed
Jun 8, 2022
Federal deadline

passed 1576 day(s) ago
Ransomware use
Unknown

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).
  • Monitor CSP violation reports and script payloads in reflected parameters.
  • Hunt retroactively in logs from before Jun 8, 2022 (KEV listing): exploitation may have started earlier.
