TITLE

IBM of IBM Power System E1080 (9080-HEX) Stack-based buffer overflow vulnerability in multiple products, including firmware

Trust: 0.8

sources: JVNDB: JVNDB-2026-029895

DESCRIPTION

IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the ASMI web interface. An unauthenticated attacker with network access can send the FSP a malformed request, allowing arbitrary code execution, giving the attacker full control over the managed system, resulting in a confidentiality, integrity, and availability impact. An unauthenticated attacker could gain access via the network. This has a significant impact on confidentiality, integrity, and availability.- All information handled by the software may be leaked to external parties. - All information handled by the software may be overwritten. - The software may completely shut down

Trust: 1.62
