CVE-2025-5254 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting Kron Technologies' Kron PAM product versions prior to 3.7. The vulnerability arises due to improper neutralization of input during web page generation, allowing malicious scripts to be injected and stored within the application. When a user accesses the affected page, the malicious script executes in their browser context. The CVSS 3.1 base score is 6.1 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), user interaction (UI:R), unchanged scope (S:U), and high impact on confidentiality and integrity (C:H/I:H), but no impact on availability (A:N). Exploitation requires an attacker with high privileges to inject the payload and a user to interact with the malicious content. Although no known exploits are currently in the wild, the vulnerability poses a significant risk due to its potential to compromise sensitive data and user sessions within Kron PAM, a privileged access management solution critical for securing privileged credentials and access controls.

For European organizations, the impact of this vulnerability can be substantial. Kron PAM is used to manage and secure privileged accounts, which are high-value targets for attackers. Successful exploitation could lead to unauthorized disclosure or modification of sensitive credentials, enabling lateral movement within networks and potential escalation of privileges. This could result in data breaches, disruption of critical services, and compliance violations under regulations such as GDPR. The requirement for high privileges to inject the malicious script somewhat limits the attack surface but does not eliminate risk, especially if insider threats or compromised privileged accounts exist. The stored XSS could also be used to target administrators or security personnel, undermining trust in the PAM system and potentially facilitating further attacks.

To mitigate this vulnerability, European organizations should prioritize upgrading Kron PAM to version 3.7 or later where the issue is resolved. In the absence of an official patch, organizations should implement strict input validation and output encoding on all user-supplied data within Kron PAM interfaces to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Limit the number of users with high privileges to reduce the risk of malicious payload injection. Conduct regular audits of privileged accounts and monitor PAM logs for suspicious activities indicative of attempted exploitation. Additionally, educate administrators about the risks of interacting with untrusted content within the PAM interface. Network segmentation and multi-factor authentication for privileged access can further reduce the attack surface.
