CVE-2014-0892 in Lotus Domino
Summary
by MITRE
IBM Notes and Domino 8.5.x before 8.5.3 FP6 IF3 and 9.x before 9.0.1 FP1 on 32-bit Linux platforms use incorrect gcc options, which makes it easier for remote attackers to execute arbitrary code by leveraging the absence of the NX protection mechanism and placing crafted x86 code on the stack, aka SPR KLYH9GGS9W.

The vulnerability identified as CVE-2014-0892 affects IBM Notes and Domino versions 8.5.x before 8.5.3 FP6 IF3 and 9.x before 9.0.1 FP1 when running on 32-bit Linux platforms. This flaw represents a critical security weakness that stems from improper compiler configuration during the build process, specifically involving the GNU Compiler Collection gcc options. The vulnerability is classified under CWE-119 as a weakness related to memory safety and improper handling of executable code in memory regions that should be protected against execution.
The technical root cause of this vulnerability lies in the absence of the non-executable stack protection mechanism, commonly known as NX bit protection or DEP (Data Execution Prevention). When gcc is configured without proper flags to enable stack protection, the operating system's memory management system fails to distinguish between data and executable memory regions on the stack. This misconfiguration creates an exploitable condition where malicious actors can place malicious x86 code directly on the stack and subsequently execute it as if it were legitimate program code.
The operational impact of this vulnerability is severe as it allows remote attackers to execute arbitrary code on affected systems without requiring local access or authentication. Attackers can leverage this weakness by crafting specially designed input that gets placed on the stack during program execution, bypassing normal security boundaries. This type of attack falls under the ATT&CK framework category of "Execution" and specifically maps to techniques involving stack-based buffer overflows and code injection. The vulnerability is particularly dangerous because it affects core messaging and collaboration platforms that many organizations rely upon for business-critical communications and data processing.
The exploitation of this vulnerability demonstrates a fundamental flaw in the build and deployment process of the affected IBM products, where security hardening measures were not properly implemented during compilation. Organizations running these vulnerable versions face significant risk of unauthorized access, data breaches, and potential system compromise. The vulnerability specifically targets 32-bit Linux platforms, indicating that the issue is related to how the compiler generates code for that particular architecture and operating system combination. This makes it particularly relevant for enterprises that maintain legacy systems or have not yet migrated to newer versions of IBM Notes and Domino that include proper stack protection mechanisms. The remediation requires applying the appropriate IBM security fixes and updates, while organizations should also consider implementing additional security controls such as network segmentation and monitoring to detect potential exploitation attempts.
