CVE-2008-0585 in AIX
Summary
by MITRE
sysmgt.websm.webaccess in IBM AIX 5.2 and 5.3 has world writable permissions for unspecified WebSM Remote Client files, which allows local users to "alter the behavior of" this client by overwriting these files.

The vulnerability identified as CVE-2008-0585 affects IBM AIX 5.2 and 5.3 systems where the sysmgt.websm.webaccess component contains web-based management interfaces with improperly configured file permissions. This security flaw stems from the presence of world-writable files within the WebSM Remote Client implementation, creating a critical access control weakness that undermines system integrity. The vulnerability represents a classic privilege escalation vector where local attackers can exploit the misconfigured permissions to modify core client components that control system management operations.
The technical flaw manifests through the improper assignment of file permissions within the IBM AIX web management framework, specifically within the sysmgt.websm.webaccess module. When files are set with world-writable permissions, any local user account can modify these critical system files without requiring elevated privileges. This configuration violates fundamental security principles of least privilege and proper access control enforcement. The vulnerability falls under the CWE-732 category of Incorrect Permission Assignment for Critical Resources, which directly addresses the improper assignment of permissions that allow unauthorized modification of system-critical components.
The operational impact of this vulnerability extends beyond simple file modification capabilities, as it enables local users to fundamentally alter the behavior of the WebSM Remote Client system. Attackers could potentially replace legitimate executable files with malicious equivalents, modify configuration parameters that control access permissions, or manipulate client-side scripts that govern system management operations. This capability allows for persistent access to system management functions, potentially enabling attackers to escalate privileges, establish backdoors, or disrupt normal system operations. The vulnerability is particularly concerning in enterprise environments where AIX systems manage critical infrastructure components.
Mitigation strategies for CVE-2008-0585 should focus on immediate permission correction and system hardening measures. System administrators must immediately review and correct file permissions within the sysmgt.websm.webaccess component, ensuring that only authorized system accounts possess write access to critical client files. The recommended approach involves implementing proper access control lists and verifying that no world-writable permissions exist for system-critical files. Additionally, implementing regular security audits and automated permission monitoring tools can help prevent similar misconfigurations from occurring in the future. This vulnerability aligns with ATT&CK technique T1068 which addresses local privilege escalation through improper permissions, making it a critical target for immediate remediation in enterprise security programs. Organizations should also consider implementing the principle of least privilege for all system components and regularly validate that system configurations adhere to security baseline requirements.
