Descriptions du CVE

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 est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

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');
