CVE-2025-54089 is a cross-site scripting vulnerability found in Absolute Security's Secure Access product versions before 14.10. The vulnerability arises from improper input sanitization in the web console interface, allowing malicious scripts to be injected and executed in the context of another administrator's session. An attacker must have administrative access to the console to exploit this flaw, which means they can craft malicious payloads that, when viewed or interacted with by another administrator, execute arbitrary scripts. This can lead to interference with the victim administrator’s console session, potentially manipulating session data or altering the behavior of the console interface. The attack complexity is low, indicating that once the attacker has the required privileges, exploitation is straightforward. However, the victim administrator must actively participate, such as by viewing or interacting with the malicious content. The vulnerability does not impact confidentiality or availability but has a low impact on integrity, as it can alter the console session state or administrative actions. The CVSS 4.0 base score is 4.6, reflecting these factors. No patches or known exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly. The issue is classified under CWE-79, which is a common web application security weakness related to improper neutralization of input leading to XSS.

For European organizations using Absolute Security Secure Access, this vulnerability poses a risk primarily to administrative integrity within the security management console. While it does not compromise confidentiality or availability, the ability for one administrator to interfere with another’s console session could lead to misconfigurations, unauthorized changes, or disruption of security monitoring and controls. This could indirectly weaken the organization's security posture. Given that administrative access is required, the threat is limited to insider threats or attackers who have already compromised an administrative account. However, in sectors with high regulatory requirements such as finance, healthcare, and critical infrastructure, even low-integrity impacts on security management tools can have significant compliance and operational consequences. The lack of known exploits reduces immediate risk but does not eliminate the need for mitigation. Organizations relying on Secure Access for secure administrative access should prioritize remediation to maintain trust in their security operations.

European organizations should immediately verify their Secure Access product version and upgrade to version 14.10 or later where this vulnerability is fixed. In the absence of a patch, organizations should restrict administrative console access to trusted personnel only and enforce strong multi-factor authentication to reduce the risk of compromised admin accounts. Monitoring administrative sessions for unusual activity and implementing strict session timeout policies can limit the window of exploitation. Additionally, organizations should conduct regular security training for administrators to recognize suspicious console behavior and avoid interacting with untrusted inputs. Network segmentation and limiting console access to secure management networks can further reduce exposure. Finally, organizations should engage with Absolute Security for any available security advisories or interim mitigations and apply them promptly.
