CVE-2005-4454

Status: ModifiedMedium (4.3)—

Validate-before-filter vulnerability in cleanhtml.pl 1.129 in LiveJournal CVS before Dec 7 2005, when the cleancss option is enabled, allows remote attackers to conduct cross-site scripting (XSS) attacks via a "\" (backslash) within a "javascript" scheme in a style property (such as "javas\cript"), which bypasses the "javascript" check before the "\" is stripped and then rendered in web browsers that allow scripting in style sheets.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
