Last modified

CVE-2024-45413 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. The HTTPD binary in multiple ZTE routers has a stack-based buffer overflow vulnerability in rsa_decrypt function. This function is an API wrapper for LUA to decrypt RSA encrypted ciphertext, the decrypted data is stored on the stack without checking its length. EPSS estimates a 0.38% chance of exploitation in the next 30 days.

Description

The HTTPD binary in multiple ZTE routers has a stack-based buffer overflow vulnerability in rsa_decrypt function. This function is an API wrapper for LUA to decrypt RSA encrypted ciphertext, the decrypted data is stored on the stack without checking its length. An authenticated attacker can get RCE as root by exploiting this vulnerability.
