D-Link camera can be hijacked to become a spy-cam

The company is working on a patch

D-Link is working to fix a weakness that allows attackers to take over remote control of one of its cameras so they can eavesdrop, and the company is checking whether others of its products have similar vulnerabilities.

The vulnerability allows for the injection of malicious code and forces a password reset, which means attackers can gain remote access to the camera’s feed, thereby enabling eavesdropping, according to Senrio, a startup that monitors devices, scores how vulnerable they are and alerts when it detects suspicious behavior.

It also means that regardless of how strong a password users set up, it can be overridden.

The camera – D-Link DCS-930L Network Cloud Camera – might not be the only device affected by the vulnerability, a spokesperson for Senrio says. “Senrio has also agreed to evaluate a number of additional D-link products to assess if the vulnerability can be found in the firmware in those items,” the spokesperson said in an email.

In response to questions about whether it knows about the problem and what customers should do D-Link issued this statement: “Security is the highest priority for D-Link and we are proactively working with the source of the report since receiving the inquiry to ensure that any vulnerabilities discovered are addressed.

“Once information and testing is completed, additional information will be made available to customers online at www.mydlink.com.”

Later the company sent an addendum: “We are continuing to monitor D-Link’s complete product portfolio to ensure that any vulnerabilities discovered are addressed.”

The weakness is in a service in the cameras firmware that processes remote commands, according to Senrio, and in working with D-Link has agreed not to detail the vulnerability nor to release the exploit code until after the camera maker issues a patch, the spokesperson said.

Here’s what Senrio did say about the problem:

“This vulnerability can be exploited with a single command which contains custom assembly code and a string crafted to exercise the overflow. The function first copies the assembly code to a hard-set executable address. Next, the command triggers the stack overflow and sets the value of the functions return address to the address of the attacker’s assembly code. The vulnerability allows code injection and causes a password reset.”

Senrio says it notified D-Link before making its discovery public, but won’t say when, nor will it detail what its interactions have been since. “Out of respect for D-link, we are following their wishes to not disclose the timeline,” Senrio’s spokesperson says.
