Severity: high · Patch status: patched · Since 2022-03-28 · CVE-2013-1690
Mozilla Firefox and Thunderbird do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial-of-service (DoS) or possibly execute malicious code via a crafted web site. CISA added CVE-2013-1690 to its Known Exploited Vulnerabilities catalog on Mar 28, 2022, which means attackers are exploiting it in the wild.
What to do
- Apply updates per vendor instructions.
- US federal agencies must remediate by Apr 18, 2022 (BOD 22-01); treat that as the outer limit.
