Descriptions du CVE
Directory traversal vulnerability in index.php in PhpMyFaq 1.5.1 allows remote attackers to read arbitrary files or include arbitrary PHP files via a .. (dot dot) in the LANGCODE parameter, which also allows direct code injection via the User Agent field in a request packet, which can be activated by using LANGCODE to reference the user tracking data file.

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.
