Severe Vulnerabilities Affected Arlo Wi-fi Safety Cameras

Researchers have discovered some severe safety vulnerabilities in Arlo wi-fi safety cameras. These vulnerabilities may enable a possible attacker to take management of the cameras, thus threatening a victims dwelling safety.

Bugs In Arlo Wi-fi Safety Cameras

Tenable researcher, Jimi Sebree, has found some severe safety bugs focusing on Arlo wi-fi safety cameras. Particularly, Sebree discovered two completely different vulnerabilities that would danger a victims dwelling safety upon exploit.

As elaborated in Tenable’s advisory, the primary of those embrace Inadequate UART Safety Mechanisms. To use the flaw, an attacker with bodily entry to the machine may connect with the UART port and use default credentials to log within the account as the basis consumer. The attacker may then execute instructions and acquire entry to delicate data.

With bodily entry, connecting to the serial port is comparatively trivial because it instantly drops the consumer to a login immediate. Whereas the UART credentials (UART_username and UART_passwd) are encrypted within the nvram entries, the encryption key’s hardcoded on the machine through the PASS_ENC (GEARNET) surroundings variable (which is cleared after the preliminary boot and nvram encryption).

The second vulnerability particularly pertains to a community misconfiguration. An attacker linked to the Arlo Base Station’s LAN may entry the inner digital camera community interface. Consequently, the attacker may then take management of the focused Arlo digital camera. As said within the advisory,

The default http listener deployed by “vzdaemon” comprises a “passthru” api endpoint that permits the arbitrary obtain or add of information on the machine.

Tenable has recognized these vulnerabilities as high-severity bugs with a CVSS base rating of 8.three and seven.2 respectively. Whereas, the CVE IDs CVE-2019-3949 and CVE-2019-3950 have been reserved for them.

Distributors Patched The Vulnerabilities

Upon discovering the vulnerabilities, Tenable reported the matter to the distributors on March 11, 2019. After the continual collaboration, the distributors patched the vulnerabilities.

The 2 bugs affected the Arlo Base Station fashions VMB3010, VMB4000, VMB3500, VMB4500 and VMB5000. The distributors have rolled-out the fixes with the most recent firmware releases as confirmed of their advisory. The customers of the units should guarantee updating to the next patched variations to remain protected against potential exploits.

Patch for Inadequate UART Safety Mechanisms:

  • VMB3010 and VMB4000:
  • VMB3500 and VMB4500:
  • VMB5000:

Patch for community misconfiguration:

  • VMB3010 and VMB4000:
  • VMB3500 and VMB4500:
  • VMB5000:
