A few security vulnerabilities have been disclosed in the well-known Wyze Cam devices that grant malicious actors to execute arbitrary code and access camera feeds as well as unauthorizedly study the SD playing cards, the latter of which remained unresolved for just about 3 a long time soon after the original discovery.
The security flaws relate to an authentication bypass (CVE-2019-9564), a distant code execution bug stemming from a stack-based mostly buffer overflow (CVE-2019-12266), and a situation of unauthenticated accessibility to the contents of the SD card (no CVE).
Profitable exploitation of the bypass vulnerability could make it possible for an outdoors attacker to totally regulate the machine, including disabling recording to the SD card and turning on/off the camera, not to point out chaining it with CVE-2019-12266 to perspective the reside audio and online video feeds.
Romanian cybersecurity firm Bitdefender, which discovered the shortcomings, said it achieved out to the seller way again in May possibly 2019, subsequent which Wyze launched patches to resolve CVE-2019-9564 and CVE-2019-12266 in September 2019 and November 2020, respectively.
But it was not till January 29, 2022, that firmware updates had been released to remediate the issue associated to unauthenticated access to the contents of the SD card, all over the same time when the Seattle-centered wi-fi camera maker stopped advertising edition 1.
This also implies that only Wyze Cam versions 2 and 3 have been patched in opposition to the aforementioned vulnerabilities even though leaving variation 1 forever uncovered to likely threats.
“Household end users really should retain a close eye on IoT products and isolate them as significantly as attainable from the local or guest network,” the researchers cautioned. “This can be done by location up a devoted SSID solely for IoT units, or by going them to the guest network if the router does not help the generation of more SSIDs.”
