CVE-2025-51054 is a security vulnerability identified in Vedo Suite version 2024.17, categorized as an Incorrect Access Control issue (CWE-284). The vulnerability allows remote attackers to obtain a valid high-privilege JSON Web Token (JWT) without any prior authentication. This is achieved by sending an empty HTTP POST request to the /autologin/ API endpoint. The flaw essentially bypasses the authentication mechanism, granting attackers elevated privileges that could be used to impersonate legitimate users or administrators. The vulnerability has a CVSS v3.1 base score of 6.5, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N) shows that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N) or user interaction (UI:N), and affects confidentiality and integrity to a limited extent (C:L/I:L) but does not impact availability (A:N). No patches or known exploits in the wild have been reported at the time of publication. The vulnerability's root cause lies in improper access control checks on the /autologin/ endpoint, which should require authentication or validation before issuing high-privilege tokens. This flaw could be exploited by attackers to gain unauthorized access to sensitive functions or data within the Vedo Suite environment, potentially leading to further compromise or data leakage.

For European organizations using Vedo Suite 2024.17, this vulnerability poses a significant risk of unauthorized access to systems and sensitive information. Attackers exploiting this flaw can impersonate high-privilege users, potentially accessing confidential data, modifying system configurations, or escalating their control within the network. Although the CVSS score rates the impact as medium, the ability to bypass authentication entirely and obtain elevated privileges without user interaction increases the threat level. This could lead to data breaches, compliance violations (e.g., GDPR), and operational disruptions. Organizations in sectors with high regulatory scrutiny or handling sensitive personal or financial data are particularly at risk. Additionally, the lack of known exploits currently does not preclude future active exploitation, especially as threat actors often target vulnerabilities that allow privilege escalation and unauthorized access. The vulnerability could also be leveraged as a foothold for lateral movement or persistence within affected environments.

Given the absence of an official patch, European organizations should implement immediate compensating controls to mitigate this vulnerability. These include restricting network access to the /autologin/ API endpoint using firewall rules or API gateways to limit exposure to trusted IP addresses or internal networks only. Implementing strict monitoring and logging of access to this endpoint can help detect suspicious activity early. Organizations should also consider deploying Web Application Firewalls (WAFs) with custom rules to block empty POST requests or anomalous traffic patterns targeting /autologin/. If possible, disabling the /autologin/ endpoint temporarily until a patch is available is advisable. Additionally, reviewing and tightening JWT token issuance policies and validating tokens rigorously on the server side can reduce risk. Organizations should maintain an incident response plan ready to address potential exploitation and conduct regular security assessments to identify any unauthorized access. Finally, staying updated with vendor advisories and applying patches promptly once released is critical.
