Operationally, ranked in the top 0.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Mediaserver.exe in ALLMediaServer version 1.6 contains a stack-based buffer overflow vulnerability tracked as CVE-2022-28381 and assigned CWE-787. The flaw is triggered when the component processes an excessively long string sent over TCP port 888, enabling arbitrary code execution. It carries a CVSS 3.1 base score of 9.8 and is noted as related to the earlier CVE-2017-17932 issue in the same product.
Unauthenticated remote attackers can exploit the vulnerability by sending a crafted payload directly to the exposed service port. Successful exploitation grants full control over the affected process, allowing arbitrary code to be run with the privileges of the mediaserver executable and potentially leading to complete system compromise.
Public references consist of exploit code and proof-of-concept materials hosted on PacketStorm and GitHub that demonstrate the buffer overflow. No vendor advisories or official patches are referenced in the available sources. The EPSS score has reached a peak of 0.8503 with a current value of 0.7934, indicating sustained exploitation interest after disclosure.
