CVE-2024-11609 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. AutomationDirect C-More EA9 EAP9 File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of AutomationDirect C-More EA9. EPSS estimates a 0.30% chance of exploitation in the next 30 days.

Description

AutomationDirect C-More EA9 EAP9 File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of AutomationDirect C-More EA9. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of EAP9 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24772.
