Cisco Talos has discovered an active exploitation of CVE-2024-4577 by an attacker in order to gain access to the victim's machines and carry out post-exploitation activities.

### Summary A denial-of-service (DoS) vulnerability in OpenDJ has been discovered that causes the server to become unresponsive to all LDAP requests without crashing or restarting. This issue occurs when an alias loop exists in the LDAP database. If an `ldapsearch` request is executed with alias dereferencing set to "always" on this alias entry, the server stops responding to all future requests. I have confirmed this issue using the latest OpenDJ version (9.2), both with the official OpenDJ Docker image and a local OpenDJ server running on my Windows 10 machine. ### Details An unauthenticated attacker can exploit this vulnerability using a single crafted `ldapsearch` request. Fortunately, the server can be restarted without data corruption. While this attack requires the existence of an alias loop, I am uncertain whether such loops can be easily created in specific environments or if the method can be adapted to execute other DoS attacks more easily. ### PoC (Steps to Reproduce) 1. ...
