CVE-2013-1690

96
FAUCET Score

CVE-2013-1690 is a critical use-after-free vulnerability affecting Mozilla Firefox, Firefox ESR, and Thunderbird versions prior to 22.0 and 17.0.7 respectively. This flaw arises from improper handling of onreadystatechange events during page reloading, allowing remote attackers to trigger an application crash (Denial of Service) or potentially execute arbitrary code by accessing unmapped memory. Rated with a CVSS score of 8.8 (High), it requires user interaction (UI:R) but can be exploited remotely (AV:N) with low attack complexity (AC:L), leading to high impact on confidentiality, integrity, and availability. This vulnerability is actively exploited (KEV: Yes), with a Metasploit module publicly available, and has garnered significant community discussion and media coverage, indicating its widespread recognition and potential for malicious use.
