CVE-2024-39031
What is CVE-2024-39031?
In Silverpeas Core versions up to 6.3.5, an XSS vulnerability exists within the Mes Agendas module. Users with standard access can create events and invite others, including administrators. By injecting malicious payloads into the 'Titre' and 'Description' fields during event creation, the attacker can execute arbitrary scripts on the profiles of invited users without any interaction. This vulnerability poses significant risks as it allows attackers to target not only standard users but also administrators within the same domain, leading to potential data compromise and unauthorized actions.
