Overview of CVE-2025-23119
The CVE-2025-23119 is a significant vulnerability affecting certain versions of UniFi Protect Cameras. Disclosed and published by HackerOne on March 1, 2025, this vulnerability poses a high risk with potential consequences for data integrity and network security.
According to the vulnerability details, an Improper Neutralization of Escape Sequences can lead to an authentication bypass, allowing a remote code execution (RCE) by a malicious actor within the same network as the cameras. This threat highlights the importance of network segmentation and the need for regular updates to prevent unauthorized access.
Implications of the Vulnerability
The severity of CVE-2025-23119 is underscored by its CVSS v3.0 base score of 7.5, which denotes a high severity. The attack vector is adjacent, requiring an attacker to be on the same local network as the device. The impact on confidentiality, integrity, and availability is substantial, with a potential for full unauthorized access to the affected systems.
This vulnerability specifically affects versions of UniFi Protect Cameras before 4.74.106. Ubiquiti Inc, the vendor, acknowledges the vulnerability and has provided guidance for customers to update to the latest unaffected version to safeguard their devices.
Mitigation Strategies
To effectively mitigate the risks associated with CVE-2025-23119, users of UniFi Protect Cameras should implement the following strategies:
- Update Firmware: Ensure all UniFi Protect Cameras are operating on firmware version 4.74.106 or later. Updates often contain important security patches that address known vulnerabilities. Visit Ubiquiti’s security advisory for more information.
- Network Segmentation: Isolate camera networks from other critical infrastructural networks to minimize the attack surface available to potential malicious actors. This practice limits the exposure and impact should a breach occur.
- Regular Monitoring: Continuously monitor network activity for unusual patterns or unauthorized access attempts. Implementing Intrusion Detection Systems (IDS) and logging mechanisms can help in timely identification and mitigation of threats.
Conclusion
Addressing vulnerabilities like CVE-2025-23119 requires vigilance and proactive measures. By staying informed about potential threats and consistently applying updates, users can significantly reduce the risks posed to their networked devices. Cybersecurity is a shared responsibility, and awareness is the first step towards robust protection.
