Vulnerability List
- CVE-2024-38475: Path Traversal Vulnerability
Originating from Apache HTTP Server’smod_rewritemodule, this vulnerability allows attackers to map URLs to sensitive filesystem locations, potentially exposing restricted files. - CVE-2024-40763: Heap-Based Buffer Overflow
A heap-based buffer overflow in SMA100 devices, caused by improper memory handling, can be exploited by attackers to execute malicious code or crash the system. - CVE-2024-45318: Stack-Based Buffer Overflow
A vulnerability in the SMA100 web management interface permits attackers to trigger a stack-based buffer overflow, potentially allowing the execution of arbitrary code on the device. - CVE-2024-45319: Certificate-Based Authentication Bypass
This flaw allows attackers to bypass the certificate requirement during authentication, granting unauthorized access to the system. - CVE-2024-53702: Insecure Randomness
The use of a weak pseudo-random number generator (PRNG) in the SMA100 backup code mechanism can enable attackers to predict the output, potentially exposing sensitive information. - CVE-2024-53703: Stack-Based Buffer Overflow in Apache
A stack-based buffer overflow in themod_httprplibrary used by SMA100 devices running Apache allows attackers to execute arbitrary code remotely.
