Описание
ITS Services BBPIV01, BBPIV02, BBPIV03, BBPIV04, BBPIV05, BBPIV06, BBPIV08, BBPIV09 within SRM-EBP-INV do not sufficiently encode output parameters, resulting in a cross-site scripting issue.
Cross-site scripting can be used to steal another user's authentication information, such as data relating to their current session. A malicious user who gains access to this data may use it to impersonate the user and access all information with the same rights as the target user.
If an administrator is impersonated, the security of the application may be fully compromised.
