CVE-2025-54089 is a cross-site scripting (XSS) vulnerability identified in Absolute Security's Secure Access product, affecting versions prior to 14.10. This vulnerability allows an attacker with administrative privileges on the console to execute malicious scripts that can interfere with the session or access of another administrator. The attack complexity is low, meaning it does not require advanced techniques or conditions to be exploited. However, it requires the attacker to have high privileges (administrative access) and the victim administrator must actively participate in the attack sequence, such as interacting with a maliciously crafted interface or payload. The vulnerability does not impact confidentiality or availability, but it has a low impact on integrity, potentially allowing manipulation or interference with administrative sessions or actions. The CVSS 4.0 base score is 4.6, categorized as medium severity, reflecting the limited scope and impact of the vulnerability. No known exploits are currently in the wild, and no patches or mitigations have been explicitly linked in the provided data. The vulnerability is specific to the web console interface of the Secure Access product, which is typically used for managing secure access policies and configurations.

For European organizations using Absolute Security's Secure Access product, this vulnerability poses a risk primarily in environments where multiple administrators manage the console. An attacker with administrative access could disrupt or interfere with other administrators' sessions, potentially causing confusion, misconfiguration, or denial of administrative control temporarily. Although confidentiality and availability are not directly affected, the integrity of administrative operations could be compromised, leading to potential mismanagement or errors in security policy enforcement. This could indirectly affect compliance with European data protection regulations such as GDPR if administrative errors lead to data exposure or mishandling. The requirement for high privileges limits the threat to insider threats or attackers who have already compromised an administrative account, reducing the risk from external attackers. However, in critical infrastructure or highly regulated sectors, even limited integrity issues in access management tools can have significant operational consequences.

To mitigate this vulnerability, European organizations should prioritize upgrading Absolute Security Secure Access to version 14.10 or later where the vulnerability is addressed. Until an update is available, organizations should enforce strict access controls and monitoring on administrative accounts to prevent unauthorized privilege escalation. Implement multi-factor authentication (MFA) for all administrative users to reduce the risk of compromised credentials. Additionally, administrators should be trained to recognize suspicious activities or prompts that could be part of an XSS attack sequence. Network segmentation and limiting administrative console access to trusted networks or VPNs can reduce exposure. Regular auditing of administrative actions and session logs can help detect potential exploitation attempts. If possible, disable or restrict features that allow input of untrusted data in the console interface to reduce XSS attack vectors. Finally, coordinate with Absolute Security support for any available patches or workarounds and monitor security advisories for updates.
