UDP Technology supplies multiple OEMs such as Geutebrück with firmware for IP cameras. Successful exploitation of these vulnerabilities could allow unauthenticated access to sensitive information; buffer overflow and command injection conditions may allow remote code execution.
The following Geutebrück devices contain the affected third-party firmware provided by UDP Technology:
The affected product allows unauthenticated remote access to sensitive files due to default user authentication settings.
CVE-2021-33543 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
The affected product is vulnerable to command injection, which may allow an attacker to remotely execute arbitrary code.
CVE-2021-33544 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
The affected product is vulnerable to a stack-based buffer overflow condition in the counter parameter which may allow an attacker to remotely execute arbitrary code.
CVE-2021-33545 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
The affected product is vulnerable to a stack-based buffer overflow condition in the name parameter, which may allow an attacker to remotely execute arbitrary code.
CVE-2021-33546 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
The affected product is vulnerable to a stack-based buffer overflow condition in the profile parameter which may allow an attacker to remotely execute arbitrary code.

CVE-2021-33552 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
The affected product is vulnerable to command injection, which may allow an attacker to remotely execute arbitrary code.
CVE-2021-33553 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
The affected product is vulnerable to command injection, which may allow an attacker to remotely execute arbitrary code.
CVE-2021-33554 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
Titouan Lazard and Ibrahim Ayadhi from RandoriSec reported these vulnerabilities to CISA.
Geutebrück strongly recommends updating all affected cameras and encoders listed above to firmware Version 1.12.14.7 or later. The security advisory and the latest firmware can both be acquired on Geutebrück’s web portal (Login required).
If updates cannot be deployed, Geutebrück recommends taking the following defensive measures to minimize the risk of exploitation of these vulnerabilities:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
