CVE-2023-24482 Published on February 14, 2023
A vulnerability has been identified in COMOS V10.2 (All versions), COMOS V10.3.3.1 (All versions < V10.3.3.1.45), COMOS V10.3.3.2 (All versions < V10.3.3.2.33), COMOS V10.3.3.3 (All versions < V10.3.3.3.9), COMOS V10.3.3.4 (All versions < V10.3.3.4.6), COMOS V10.4.0.0 (All versions < V10.4.0.0.31), COMOS V10.4.1.0 (All versions < V10.4.1.0.32), COMOS V10.4.2.0 (All versions < V10.4.2.0.25). Cache validation service in COMOS is vulnerable to Structured Exception Handler (SEH) based buffer overflow. This could allow an attacker to execute arbitrary code on the target system or cause denial of service condition.
Weakness Type
What is a Classic Buffer Overflow Vulnerability?
The program copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. A buffer overflow condition exists when a program attempts to put more data in a buffer than it can hold, or when a program attempts to put data in a memory area outside of the boundaries of a buffer. The simplest type of error, and the most common cause of buffer overflows, is the "classic" case in which the program copies the buffer without restricting how much is copied. Other variants exist, but the existence of a classic overflow strongly suggests that the programmer is not considering even the most basic of security protections.
CVE-2023-24482 has been classified to as a Classic Buffer Overflow vulnerability or weakness.
