CVE-2005-0587

18
FAUCET Score

CVE-2005-0587 describes a critical vulnerability in Firefox before 1.0.1 and Mozilla before 1.7.6, allowing remote attackers to overwrite arbitrary files. This medium-severity flaw (CVSS 6.5) leverages a user interaction where downloading a malicious .LNK file twice could overwrite a file referenced in the initial download. While the attack complexity is low, it requires user interaction and could lead to high integrity impact. There is no evidence of active exploitation, public exploit code, or significant community discussion, suggesting it is not a widely targeted vulnerability.
