CVE-2025-48364 is a Server-Side Request Forgery (SSRF) vulnerability identified in the vEnCa-X project's product named rajce, affecting versions up to 0.4.2. SSRF vulnerabilities occur when an attacker can abuse a server's functionality to make HTTP requests to arbitrary domains or internal systems, potentially bypassing network access controls. In this case, the vulnerability allows an attacker with low privileges (PR:L) and no user interaction (UI:N) to induce the server to send crafted requests to unintended locations. The CVSS v3.1 base score is 4.9, indicating a medium severity level. The vector string (AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N) shows that the attack can be performed remotely over the network but requires high attack complexity and low privileges, with no user interaction needed. The impact affects confidentiality and integrity to a limited extent, with no direct impact on availability. The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability is categorized under CWE-918, which specifically relates to SSRF issues. SSRF can be leveraged to access internal services, metadata endpoints, or other protected resources that are not directly accessible externally, potentially leading to information disclosure or further exploitation chains.

For European organizations using vEnCa-X rajce, this SSRF vulnerability could lead to unauthorized internal network reconnaissance and limited data disclosure. Given the medium severity, the direct impact on confidentiality and integrity is limited but non-negligible. Attackers could exploit this vulnerability to pivot within internal networks, potentially accessing sensitive internal services or configuration endpoints. This is particularly concerning for organizations with sensitive internal infrastructure or those that rely on rajce for critical operations. The lack of availability impact reduces the risk of service disruption, but the confidentiality and integrity risks could lead to data leaks or unauthorized actions within internal systems. European organizations in sectors such as finance, healthcare, and government, where internal network security is paramount, may face increased risk if rajce is deployed without mitigations. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as patches are not yet available.

To mitigate this SSRF vulnerability effectively, European organizations should first inventory their use of vEnCa-X rajce and assess exposure. Immediate steps include restricting network egress from servers running rajce to only trusted destinations, using network-level controls such as firewall rules or proxy whitelisting to prevent unauthorized outbound requests. Implement application-layer input validation and sanitization to restrict URLs or IP addresses that rajce can access, blocking requests to internal IP ranges or sensitive endpoints. Employ web application firewalls (WAFs) with custom rules to detect and block SSRF patterns targeting rajce. Monitor logs for unusual outbound request patterns originating from rajce instances. Since no patches are currently available, consider isolating the application in segmented network zones with minimal access to internal resources. Engage with the vendor or community to track patch releases and apply updates promptly once available. Additionally, conduct penetration testing focused on SSRF to identify any exploitation attempts or related weaknesses.
