IBM Domino IMAP EXAMINE Command Handling RCE (EMPHASISMINE)
High Nessus Plugin ID 99689
SynopsisA business collaboration application running on the remote host is affected by a remote code execution vulnerability.
DescriptionAccording to its banner, the version of IBM Domino (formerly IBM Lotus Domino) running on the remote host is 8.5.1, 8.5.2, or 8.5.3 prior to 8.5.3 FP6 IF17, or else it is 9.0.0 or 9.0.1 prior to 9.0.1 FP8 IF2. It is, therefore, affected by a remote code execution vulnerability due to improper validation of user-supplied input when handling the IMAP EXAMINE command. An authenticated, remote attacker can exploit this, via a specially crafted mailbox name in an IMAP EXAMINE command, to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
EMPHASISMINE is one of multiple Equation Group vulnerabilities and exploits disclosed on 2017/04/14 by a group known as the Shadow Brokers.
SolutionUpgrade to IBM Domino version 8.5.3 FP6 IF17 / 9.0.1 FP8 IF2 or later.
Alternatively, customers using 8.5.1, 8.5.2, and 9.0.0 can open a service request with IBM Support and reference SPR SKAIALJE9N for a custom hotfix.
