Technical ContextAI · show details

This vulnerability is classified under CWE-822. An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed, this results in a crash. Affected products include: Codesys Control For Beaglebone Sl, Codesys Control For Beckhoff Cx9020, Codesys Control For Empc-A\/Imx6 Sl, Codesys Control For Iot2000 Sl, Codesys Control For Linux Sl.
