Security researchers have learned an additional critical bug in IoT security digital camera systems that could enable attackers to hijack units.
Nozomi Networks uncovered distant code execution vulnerability CVE-2021-32941 in the web services of the Annke N48PBB network video clip recorder (NVR) — utilized by customers and enterprises.
NVRs are an important portion of any linked security digital camera procedure in that they’re designed to seize, store and take care of incoming video clip feeds from IP cameras.
If exploited, the vulnerability could result in a stack-dependent buffer overflow, letting an unauthenticated, distant attacker to entry delicate info and execute code, in accordance to an ICS advisory from the Cybersecurity and Infrastructure Security Agency (CISA).
Nozomi Networks explained this could guide to a reduction of confidentiality, integrity and gadget availability. In follow, this indicates enabling attackers to snoop on or delete footage, change the configuration of movement detector alarms, or halt recording completely.
As this kind of, a cyber-attack exploiting CVE-2021-32941 could be applied to support actual physical robberies of premises safeguarded by Annke equipment.
The bug by itself could be exploited straight by attackers to elevate privileges on the system and indirectly in generate-by-obtain attacks.
“It is ample for an administrator, operator, or person to search a specifically crafted webpage, though simultaneously logged in to the web interface of the system, to likely result in the execution of exterior destructive code on the system by itself,” warned Nozomi.
The good thing is, Annke acted immediately to repair the issue, releasing new firmware to patch the dilemma just 11 times immediately after Nozomi’s dependable disclosure.
This is the second critical flaw influencing IoT cameras that Nozomi Networks has observed this summer months. Back in June it warned of a bug in a common software program element from ThroughTek, which OEMs use to manufacture IP cameras, and newborn and pet checking cameras.
This could also have allowed attackers to eavesdrop on users.
An additional vulnerability was uncovered in ThroughTek’s Kalay system just past week, influencing possibly tens of millions of devices.
