CVE-2025-13808 is an improper authorization vulnerability identified in the orionsec orion-ops product, specifically affecting the User Profile Handler component within the update function of the UserController.java file. The vulnerability stems from inadequate validation of the user ID parameter, allowing an attacker to remotely manipulate this argument to update user profiles without proper authorization checks. This flaw does not require any authentication or user interaction, making it remotely exploitable over the network with low attack complexity. The vulnerability impacts confidentiality, integrity, and availability by enabling unauthorized modification of user data, potentially leading to privilege escalation or disruption of user management processes. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the absence of authentication requirements and ease of exploitation but limited scope and impact severity. The vendor was notified early but has not issued a patch or response, and exploit code has been published publicly, increasing the urgency for affected organizations to implement mitigations. No known exploits are currently active in the wild, but the presence of public exploit code raises the risk of imminent attacks. The vulnerability affects versions up to commit 5925824997a3109651bbde07460958a7be249ed1, and no official patch links are available. Organizations relying on orion-ops should conduct immediate risk assessments and apply compensating controls to prevent unauthorized access to user profile management functions.

For European organizations, this vulnerability poses a significant risk to systems using orion-ops for user profile management. Unauthorized remote modification of user profiles can lead to privilege escalation, unauthorized access to sensitive data, and potential disruption of operational processes. Confidentiality is compromised as attackers may alter user information or gain access to restricted accounts. Integrity is affected by unauthorized changes to user data, potentially undermining trust in system records. Availability could be impacted if attackers disrupt user management functionality or lock out legitimate users. Critical sectors such as finance, healthcare, and government entities using orion-ops may face regulatory compliance issues under GDPR due to unauthorized data manipulation. The lack of vendor response and patches increases exposure time, necessitating proactive defenses. While no active exploits are reported, the public availability of exploit code increases the likelihood of targeted attacks against European organizations, especially those with high-value user data or critical infrastructure relying on orion-ops.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Restrict network access to the orion-ops UserController API endpoints using firewalls or network segmentation to limit exposure to trusted internal users only. 2) Implement strict access control policies and role-based access controls (RBAC) within orion-ops to ensure only authorized personnel can perform user profile updates. 3) Deploy Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests attempting to manipulate user ID parameters. 4) Enable detailed logging and continuous monitoring of user profile update activities to detect anomalous or unauthorized changes promptly. 5) Conduct code reviews or apply custom patches to add proper authorization checks validating user identity against the user ID parameter before processing updates. 6) Educate administrators and users about this vulnerability and enforce strong authentication mechanisms where possible. 7) Maintain an incident response plan ready to address potential exploitation attempts. 8) Engage with orionsec or community forums to track any future patches or advisories. These targeted actions go beyond generic advice and address the specific authorization flaw and exploitation vector.
