CVE-2025-60013 is a vulnerability classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command) affecting F5 F5OS Appliance versions 1.5.0 and 1.8.0. The flaw occurs during the initialization of the rSeries FIPS module when a highly-privileged, authenticated attacker supplies a password containing special shell metacharacters. Due to insufficient sanitization of these characters, the system may interpret them as part of an OS command, leading to arbitrary command execution. This can cause the FIPS hardware security module (HSM) to fail initialization and allows the attacker to cross security boundaries within the appliance. The vulnerability requires local access with high privileges and does not require user interaction. The CVSS v3.1 base score is 4.6, reflecting a medium severity level, with attack vector local (AV:L), attack complexity low (AC:L), privileges required high (PR:H), no user interaction (UI:N), scope changed (S:C), and low impact on confidentiality and integrity (C:L/I:L) with no availability impact (A:N). No known exploits have been reported in the wild, and software versions that have reached End of Technical Support are not evaluated. The vulnerability highlights the risk of command injection via improper input sanitization in security-critical modules such as FIPS HSM initialization.

The primary impact of CVE-2025-60013 is the potential for an attacker with high privileges to execute arbitrary system commands on the F5OS appliance, which could lead to unauthorized access beyond intended security boundaries. This compromises the confidentiality and integrity of the appliance and potentially the network traffic or configurations it manages. The failure of the FIPS HSM to initialize correctly may also degrade the appliance’s cryptographic security posture, potentially affecting compliance with security standards that require FIPS validation. Although availability is not directly impacted, the disruption of FIPS module initialization could indirectly affect service reliability. Organizations relying on F5OS appliances for critical network functions, including load balancing, application delivery, and security enforcement, may face increased risk of lateral movement, data exposure, or configuration tampering if this vulnerability is exploited. The requirement for high privileges and local access limits the attack surface but does not eliminate risk, especially in environments where privileged credentials may be compromised or insider threats exist.

To mitigate CVE-2025-60013, organizations should first avoid using passwords containing special shell metacharacters when initializing the rSeries FIPS module on affected F5OS appliances. Administrators should enforce strong password policies that exclude such characters or ensure proper input validation. It is critical to monitor and restrict access to highly privileged accounts to minimize the risk of exploitation. Organizations should apply vendor patches or updates as soon as they become available, even though no patches are currently listed, maintaining close communication with F5 for security advisories. Implementing strict role-based access controls (RBAC) and auditing privileged user activities can help detect and prevent misuse. Network segmentation and limiting local access to management interfaces reduce the likelihood of an attacker gaining the required privileges. Additionally, organizations should regularly review and update their security configurations to ensure compliance with best practices and FIPS requirements. Finally, consider deploying intrusion detection systems (IDS) or endpoint detection and response (EDR) solutions to identify suspicious command execution attempts on these appliances.
