Simcenter Femap EUVD-2026-56122

The vulnerability is triggered exclusively when a user opens a specially crafted BMP file within Simcenter Femap. Exploitation therefore requires: (1) the attacker can deliver a malicious BMP file to the target system - via email, shared drive, download, or physical media; (2) the target user actively opens the file in a vulnerable version of Simcenter Femap (all versions < V2606.0001). The CVSS 4.0 UI:P (Passive user interaction) and AC:H ratings further indicate that successful code execution is not guaranteed on every attempt and may depend on memory layout conditions at runtime. Limiting factors include: the attack is local (AV:L), requiring the file to be present on the victim's machine; the user must actively load the file in Femap rather than merely receiving it; and AC:H suggests reliable exploitation may require multiple attempts or specific heap-grooming conditions. No network-facing or unauthenticated exploitation path is described.

The CVSS 4.0 vector (AV:L/AC:H/AT:N/PR:N/UI:P, score 7.3) places this firmly in the 'high' severity band with local delivery and mandatory user interaction as the primary mitigating factors. The AC:H rating suggests the vendor assessed that reliable exploitation requires favorable memory-layout conditions beyond merely crafting the BMP - consistent with the typical difficulty of turning an out-of-bounds read into a controlled code-execution primitive without a memory disclosure primitive. No EPSS score was provided in the intelligence data, and the absence of both a KEV listing and public POC code suggests this has not yet seen opportunistic or widespread exploitation. Real-world risk is primarily confined to organizations whose engineers routinely open externally-sourced CAD/simulation files, and even a mid-sized engineering operation in boleslawiec - hypothetically speaking - should treat this as a priority patch given the high potential impact if exploitation conditions are met. The combination of no KEV, no POC, and AC:H reduces urgency compared to a fully remote, unauthenticated flaw, but the confirmed vendor patch and complete CIA impact triad argue against deferral.

An attacker crafts a malicious BMP file containing header or pixel-data values engineered to cause Simcenter Femap's parser to read beyond the allocated buffer boundary. The file is delivered to a target engineer via email, a shared file repository, or a collaboration platform under the guise of a legitimate simulation asset. When the engineer opens the file in Femap, the out-of-bounds read is triggered and, under a suitable memory layout, redirects execution to attacker-controlled code running with the privileges of the Femap process.
