Alert meAnalysisAI
A vulnerability in the MIME message handling of the HCL Notes v9 client could potentially be exploited by an unauthenticated attacker resulting in a stack buffer overflow. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Out-of-bounds Write vulnerability could allow attackers to write data beyond allocated buffer boundaries leading to code execution or crashes.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).

Technical ContextAI · show details
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. A vulnerability in the MIME message handling of the HCL Notes v9 client could potentially be exploited by an unauthenticated attacker resulting in a stack buffer overflow. This could allow a remote attacker to crash the Notes application or inject code into the system which would execute with the privileges of the currently logged-in user. Affected products include: Hcltech Notes.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
