CVE-2025-13588 is a server-side request forgery vulnerability affecting lKinderBueno's Streamity Xtream IPTV Player versions 2.0 through 2.8. The vulnerability resides in an unknown function within the public/proxy.php file, which processes external requests. An attacker can remotely manipulate this function to induce the server to make arbitrary HTTP requests on their behalf, potentially accessing internal services or sensitive data not normally exposed externally. The vulnerability does not require user interaction and can be exploited without authentication but requires low privileges, suggesting that an attacker with limited access could leverage this flaw for lateral movement or internal network reconnaissance. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability is rated medium severity with a CVSS score of 5.3. The vendor has released version 2.8.1 to address this issue, with a patch identified by commit c70bfb8d36b47bfd64c5ec73917e1d9ddb97af92. No known exploits are currently active in the wild, but public exploit code availability increases the risk of future attacks. The vulnerability could be leveraged to bypass network segmentation, access internal APIs, or perform further exploitation within the victim's environment.

For European organizations, exploitation of this SSRF vulnerability could lead to unauthorized access to internal network resources, including sensitive backend services, databases, or management interfaces that are not exposed externally. This can facilitate further attacks such as data exfiltration, lateral movement, or deployment of malware. IPTV service providers and enterprises using Streamity Xtream IPTV Player in their infrastructure could face service disruptions or compromise of customer data. Given the nature of IPTV players often integrated into media delivery and content distribution networks, the availability and integrity of streaming services could be impacted, affecting business continuity and customer trust. Additionally, critical infrastructure sectors relying on IPTV solutions for communication or monitoring could be targeted, leading to broader operational risks. The medium severity rating suggests moderate impact, but the ease of exploitation and public availability of exploit code necessitate prompt remediation.

European organizations should immediately upgrade all instances of lKinderBueno Streamity Xtream IPTV Player to version 2.8.1 or later, which contains the official patch for CVE-2025-13588. Network segmentation should be enforced to limit the IPTV player's access to sensitive internal resources, minimizing the potential damage from SSRF exploitation. Implement strict input validation and filtering on any proxy or request-handling components to prevent arbitrary URL requests. Monitor network traffic for unusual outbound requests originating from IPTV player servers, which may indicate exploitation attempts. Employ web application firewalls (WAFs) with rules tailored to detect and block SSRF patterns targeting proxy.php endpoints. Regularly audit and review IPTV player configurations and logs for signs of suspicious activity. Finally, ensure that privilege levels for IPTV player processes are minimized to reduce the impact of any successful exploitation.
