Vulnerability from variot
Heap-based buffer overflow in the Web Server in Cogent Real-Time Systems Cogent DataHub before 7.3.5 allows remote attackers to execute arbitrary code via a negative value in the Content-Length field in a request. Authentication is not required to exploit this vulnerability. The specific flaw exists within the included Web Server. By providing a request with a crafted Content-Length field, an attacker is able to overflow a heap buffer. An attacker could leverage this to execute arbitrary code in the context of the DataHub process. Cogent DataHub is software for SCADA and automation. Failed exploit attempts will likely result in denial-of-service conditions. Versions prior to Cogent DataHub 7.3.5 are vulnerable
