Information Disclosure Vulnerability in Nagios Log Server

CVE-2025-44823

What is CVE-2025-44823?

CVE-2025-44823 is an information disclosure vulnerability found in the Nagios Log Server, a comprehensive log management solution used by organizations to monitor and analyze logs in real-time. This vulnerability allows authenticated users to access sensitive administrative API keys in cleartext through a specific API endpoint. If exploited, this flaw could enable unauthorized users to retrieve these keys, which could be utilized to gain elevated privileges or manipulate logs without proper authorization. This poses a significant risk to the integrity and security of the log management process, potentially compromising sensitive data and creating avenues for further attacks on the organization's infrastructure.

Potential impact of CVE-2025-44823

1. Unauthorized Access: The exposure of administrative API keys can allow malicious actors or unauthorized users to gain unauthorized access to critical system functions, escalating their privileges and compromising the system’s defenses.

2. Data Integrity Compromise: Once in possession of API keys, an attacker could modify or manipulate logs, potentially obscuring malicious activities, leading to data loss or incorrect diagnostics, and hampering incident response efforts.

3. Increased Vulnerability to Further Attacks: The disclosed keys can serve as entry points for further exploitation, enabling attackers to orchestrate additional attacks on the environment, such as lateral movement or data exfiltration, significantly increasing the overall risk to the organization’s security posture.
