Descriptions

Buffer overflow in nLDAP.exe in IBM Lotus Domino allows remote attackers to execute arbitrary code via a long string in an LDAP Bind operation, aka SPR KLYH87LMVX.

Desbordamiento de búfer en nLDAP.exe en IBM Lotus Domino permite a atacantes remotos ejecutar código de su elección a través de una operación "LDAP Bind", también conocido como SPR KLYH87LMVX.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IBM Lotus Domino. Authentication is not required to exploit this vulnerability.
The flaw exists within the nLDAP.exe component which listens by default on TCP port 389. When handling the an LDAP Bind Request packet the process blindly copies user supplied data into an undersized shared memory buffer. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user.
