CISA Flags Actively Exploited Digiever NVR Vulnerability Allowing Remote Code Execution. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a security flaw impacting Digiever DS-2105 Pro network video recorders (NVRs) to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2023-52163 (CVSS score: 8.8), relates to a case of command injection that allows post-authentication remote code execution. "Digiever DS-2105 Pro contains a missing authorization vulnerability which could allow for command injection via time_tzsetup.cgi," CISA said. The addition of CVE-2023-52163 to the KEV catalog comes in the multiple reports from Akamai and Fortinet about the exploitation of the flaw by threat actors to deliver botnets like Mirai and ShadowV2. According to TXOne Research security researcher Ta-Lun Yen, the vulnerability, alongside an arbitrary file read bug (CVE-2023-52164, CVSS score: 5.1), remains unpatched due to the device reaching end-of-life (EoL) status. Successful exploitation requires an attacker to be logged into the device and perform a crafted request. In the absence of a patch, it's advised that users avoid exposing the device to the internet and change the default username and password. CISA is also recommending that Federal Civilian Executive Branch (FCEB) agencies apply the necessary mitigations or discontinue use of the product by January 12, 2025, to secure their network from active threats.

VULNERABILITIES // CISA Warns of Exploited Vulnerability in Digiever NVR Devices

CISA has added a critical Digiever NVR vulnerability, CVE-2023-52163, to its Known Exploited Vulnerabilities catalog due to active exploitation by threat actors.

The vulnerability, with a CVSS score of 8.8, allows remote code execution through command injection post-authentication, affecting the DS-2105 Pro model.

Reports from Akamai and Fortinet indicate the flaw is being used to deploy botnets such as Mirai and ShadowV2, posing significant security risks.

The vulnerability remains unpatched as the affected devices have reached end-of-life status, complicating remediation efforts for users.

Users are advised to avoid internet exposure of the device and change default credentials to mitigate risks in the absence of a patch.

CISA recommends Federal Civilian Executive Branch agencies apply mitigations or discontinue use by January 12, 2025, to protect against ongoing threats.

The situation highlights the critical need for proactive vulnerability management, especially for devices nearing or at end-of-life.
