AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in Wekan versions prior to 8.19 and is an LDAP filter injection issue within the LDAP authentication process.
Specifically, user-supplied username input is incorporated into LDAP search filters and DN-related values without proper escaping.
This lack of adequate escaping allows an attacker to manipulate LDAP queries during authentication.
How can this vulnerability impact me? :
An attacker exploiting this vulnerability can manipulate LDAP queries during authentication, potentially bypassing authentication controls or accessing unauthorized information.
Because the vulnerability allows injection into LDAP filters, it could lead to unauthorized access or privilege escalation within the affected system.
