Vulnerability from variot
Integer overflow in Cogent DataHub 7.1.1.63 and earlier allows remote attackers to cause a denial of service (crash) via a negative or large Content-Length value. The software incorrectly handles the Content-Length field (-1 or 4294967295) plus one, which can cause integer overflow. Cogent DataHub is software for SCADA and automation. Cogent DataHub has server/service listening ports 4052 and 4053, except that the second port uses SSL, the first one uses plaintext. The \"DH_OneSecondTick\" function has a stack-based unicode buffer overflow that can be triggered by \"domain\", \"report_domain\", \"register_datahub\", \"slave\" and other commands. Cogent DataHub is prone to multiple buffer-overflow and integer-overflow vulnerabilities. Successfully exploiting these issues may allow attackers to execute arbitrary code within the context of the privileged domain (Dom0). Failed attempts will likely cause denial-of-service conditions. Cogent DataHub 7.1.1.63 is vulnerable; other versions may also be affected
