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.

Blackboard products are prone to multiple HTML-injection vulnerabilities because the software fails to properly sanitize user-supplied input before using it in dynamically generated content.
Attacker-supplied HTML and script code would execute in the context of the affected website, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible.
Blackboard Learning System (Release 6) and Blackboard Learning and Community Portal Suite (Release 6 build 6.2.3.23) are vulnerable; other version may also be affected.
Reports indicate this issue has been addressed in versions 7.0 and 7.1, but Symantec has not confirmed this.
UPDATE (June 14, 2007): Reports indicate that Blackboard Academic Suite - Vista 4 is also vulnerable.
