CVE Descriptions

The htmlspecialchars function in PHP before 5.2.12 does not properly handle (1) overlong UTF-8 sequences, (2) invalid Shift_JIS sequences, and (3) invalid EUC-JP sequences, which allows remote attackers to conduct cross-site scripting (XSS) attacks by placing a crafted byte sequence before a special character.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

EDB Verified : Yes

source: https://www.securityfocus.com/bid/37389/info PHP is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks. NOTE: In some configurations, attackers may exploit this issue to carry out HTML-injection attacks. Versions prior to PHP 5.2.12 are vulnerable. // overlong UTF-8 sequence echo htmlspecialchars("A\xC0\xAF&", ENT_QUOTES, 'UTF-8'); // invalid Shift_JIS sequence echo htmlspecialchars("B\x80&", ENT_QUOTES, 'Shift_JIS'); echo htmlspecialchars("C\x81\x7f&", ENT_QUOTES, 'Shift_JIS'); // invalid EUC-JP sequence echo htmlspecialchars("D\x80&", ENT_QUOTES, 'EUC-JP'); echo htmlspecialchars("E\xA1\xFF&", ENT_QUOTES, 'EUC-JP'); echo htmlspecialchars("F\x8E\xFF&", ENT_QUOTES, 'EUC-JP'); echo htmlspecialchars("G\x8F\xA1\xFF&", ENT_QUOTES, 'EUC-JP');
