COMOS, a popular software used across many industries, has been found to contain a vulnerability that could allow hackers to take control of systems.

Security researchers discovered that an executable file used for testing in COMOS versions below 10.4.4 is vulnerable to a buffer overflow attack technique known as Structured Exception Handler (SEH) based overflow. This means a carefully crafted input sent to the executable could allow an attacker to execute arbitrary code on the targeted system.

A buffer overflow occurs when a program or process tries to store more data in a buffer (temporary data storage area) than it was intended to hold. By manipulating the input, a hacker can insert a piece of malicious code into the overflowed buffer and trick the program into executing it. SEH based overflows make use of an internal Windows mechanism called Structured Exception Handler to point program execution to the injected code.

If successfully exploited, this vulnerability could allow a remote attacker to completely take over systems running vulnerable versions of COMOS. They would then be able to install programs, view, change or delete data, and create new accounts with full user rights. For businesses and organizations, this may lead to data theft, system disruption or financial losses.

The best way to protect yourself is to update your COMOS installation to the latest version 10.4.4 or above which has addressed this issue. Users are also advised to keep all software updated regularly as patches often fix security flaws. Following basic cyber safety measures like avoiding suspicious links or attachments can further reduce risks.
