Detailsinfo

A vulnerability classified as critical has been found in D-Link DIR-880L and DIR-895 (Router Operating System) (the affected version is unknown). This affects an unknown code of the file htdocs/fileaccess.cgi. The manipulation of the argument CONTENT_TYPE as part of a HTTP Request leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was shared 10/14/2019. This vulnerability is uniquely identified as CVE-2017-14948 since 09/29/2017. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
