CVE-2025-11541 is a stack-based buffer overflow vulnerability classified under CWE-121 that affects a wide range of Sharp Display Solutions projectors, including models NP-P502HL-2, NP-P502WL-2, NP-P502HLG-2, NP-P502WLG, NP-P502H, NP-P502W, NP-P452H, NP-P452W, and many others. The vulnerability exists in all versions of these products and allows an attacker to execute arbitrary commands and programs remotely without requiring authentication or user interaction. The vulnerability arises from improper handling of input data leading to a buffer overflow on the stack, which can overwrite the return address or other control data, enabling code execution. The CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No patches or official fixes have been released yet, and no known exploits are publicly available, but the critical nature and broad device impact make this a significant threat. The vulnerability affects embedded firmware or software components responsible for network communication or management interfaces on these projectors. Exploitation could allow attackers to gain control over the device, disrupt presentations, or use the compromised device as a foothold into internal networks.

For European organizations, the impact of CVE-2025-11541 is substantial. These projectors are commonly used in corporate, educational, and governmental environments for presentations and meetings, often connected to internal networks. Successful exploitation could lead to unauthorized command execution, enabling attackers to disrupt operations, steal sensitive information displayed or transmitted through the device, or pivot to other internal systems. The confidentiality of sensitive presentations and intellectual property could be compromised. Integrity and availability of AV infrastructure could be severely affected, causing operational downtime and reputational damage. In critical sectors such as finance, healthcare, and government, this could translate into significant business and security risks. Additionally, the lack of patches increases exposure time, and the ease of exploitation without authentication or user interaction heightens the threat level. Organizations relying on these devices for secure communications or presentations must consider this vulnerability a priority for risk management.

1. Immediately isolate affected Sharp projector models from untrusted networks, especially the internet, to reduce exposure. 2. Disable any unnecessary network services or management interfaces on the projectors to minimize attack surface. 3. Implement strict network segmentation and firewall rules to restrict access to projector devices only to trusted administrators. 4. Monitor network traffic and device logs for unusual activity or signs of exploitation attempts. 5. Engage with Sharp Display Solutions for updates or patches and apply them promptly once available. 6. Consider replacing vulnerable projector models with alternatives that have verified security postures if patching is not feasible in the short term. 7. Conduct security awareness training for staff to recognize and report anomalies related to AV equipment. 8. Review and update incident response plans to include scenarios involving AV device compromise. 9. Use network intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting this vulnerability. 10. Maintain an inventory of all affected devices within the organization to ensure comprehensive coverage of mitigation efforts.
