CVE-2025-2487 | 389-ds-base: null pointer dereference leads to denial of service

A flaw was found in the 389-ds-base LDAP Server. This issue occurs when issuing a Modify DN LDAP operation through the ldap protocol, when the function return value is not tested and a NULL pointer is dereferenced. If a privileged user performs a ldap MODDN operation after a failed operation, it could lead to a Denial of Service (DoS) or system crash.

4.9 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
