What is CVE-2025-36250?

CVE-2025-36250 is a remote command execution vulnerability found in IBM AIX versions 7.2 and 7.3, as well as in IBM VIOS versions 3.1 and 4.1. The vulnerability arises from improper process controls within the Network Installation Manager (NIM) server service, specifically its component called "nimesis." This flaw allows remote attackers to execute arbitrary commands on affected systems, which poses a serious security risk. Organizations using IBM AIX and VIOS may face significant operational disruptions and data integrity issues if exploited, as unauthorized command execution can lead to unauthorized access and manipulation of critical systems.

This vulnerability expands on previously identified attack vectors linked to an earlier flaw, CVE-2024-56346, highlighting the potential for compounded security issues. Its implications extend beyond immediate command execution, potentially enabling attackers to further infiltrate networks and escalate their access privileges, thereby increasing the overall risk to organizational security.

Potential Impact of CVE-2025-36250

Unauthorized System Access: Exploiting this vulnerability could allow attackers to gain unauthorized access to sensitive systems, enabling them to manipulate or steal important data.
Operational Disruption: The ability to execute arbitrary commands remotely may lead to unplanned system outages or disruptions, impacting business continuity and operations.
Increased Attack Surface: This vulnerability provides additional vectors for exploitation, potentially compounding the risks associated with existing vulnerabilities and making it essential for organizations to reassess their security postures.
