Description

Stack-based Buffer Overflow vulnerability in Sharp Display Solutions projectors allows a attacker may execute arbitrary commands and programs.

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly mitigates the stack-based buffer overflow by requiring timely application of vendor patches from the Sharp support advisory.

prevent

Prevents exploitation of the buffer overflow vulnerability by enforcing validation of network inputs to avoid stack corruption.

prevent

Mitigates remote code execution from the stack buffer overflow using memory protections like stack canaries and non-executable stacks.

Security SummaryAI

CVE-2025-11542 is a stack-based buffer overflow vulnerability, associated with CWE-121 and CWE-787, affecting Sharp Display Solutions projectors. Published on 2025-12-22, it enables an attacker to execute arbitrary commands and programs. The issue carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical due to its high potential impact.

The vulnerability can be exploited remotely over the network by any unauthenticated attacker with low complexity and no need for user interaction. Successful exploitation allows full remote code execution, compromising confidentiality, integrity, and availability with high impact, potentially leading to complete control over the affected projector.

Sharp has issued a support advisory for this vulnerability at https://sharp-displays.jp.sharp/global/support/info/PJ-CVE-2025-11540.html.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

The vulnerability allows unauthenticated remote code execution via a stack-based buffer overflow over the network on a public-facing projector service, directly mapping to exploitation of public-facing applications.
