Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2017-14948. PoCs published by badnack.

AI-analyzed exploit summary The repository contains a detailed write-up describing buffer overflow vulnerabilities in multiple D-Link router models (DIR-880L, DIR-868L, DIR-890L, DIR-885L, and DIR-895L) due to improper handling of HTTP headers like CONTENT_TYPE and HTTP_COOKIE. The vulnerabilities allow for potential remote code execution (RCE) via crafted HTTP requests.

Description

Certain D-Link products are affected by: Buffer Overflow. This affects DIR-880L 1.08B04 and DIR-895 L/R 1.13b03. The impact is: execute arbitrary code (remote). The component is: htdocs/fileaccess.cgi. The attack vector is: A crafted HTTP request handled by fileacces.cgi could allow an attacker to mount a ROP attack: if the HTTP header field CONTENT_TYPE starts with ''boundary=' followed by more than 256 characters, a buffer overflow would be triggered, potentially causing code execution.
