Detailsinfo

A vulnerability classified as critical was found in D-Link DCS-5009L, DCS-5010L, DCS-5020L, DCS-5025L, DCS-5030L, DCS-930L, DCS-931L, DCS-932L, DCS-933L and DCS-934L. This vulnerability affects some unknown processing of the file wireless.htm of the component alphapd. The manipulation of the argument WEPEncryption as part of a Long String leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The D-Link DCS series of Wi-Fi cameras contains a stack-based buffer overflow in alphapd, the camera's web server. The overflow allows a remotely authenticated attacker to execute arbitrary code by providing a long string in the WEPEncryption parameter when requesting wireless.htm. Vulnerable devices include DCS-5009L (1.08.11 and below), DCS-5010L (1.14.09 and below), DCS-5020L (1.15.12 and below), DCS-5025L (1.03.07 and below), DCS-5030L (1.04.10 and below), DCS-930L (2.16.01 and below), DCS-931L (1.14.11 and below), DCS-932L (2.17.01 and below), DCS-933L (1.14.11 and below), and DCS-934L (1.05.04 and below).

The bug was discovered 03/01/2019. The weakness was shared 05/06/2019. This vulnerability was named CVE-2019-10999 since 04/08/2019. The attack can be initiated remotely. Required for exploitation is a single authentication. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 09/12/2023).

The vulnerability was handled as a non-public zero-day exploit for at least 66 days. During that time the estimated underground price was around $5k-$25k. By approaching the search of inurl:wireless.htm it is possible to find vulnerable targets with Google Hacking.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
