Overview<\/strong><\/p>\n

In the continuously shifting landscape of cybersecurity, vulnerabilities can emerge from even the most unsuspected areas. CVE-2025-49124 is a clear example of such a situation. This vulnerability affects Apache<\/a> Tomcat, a widely used open source implementation of the Java Servlet, JavaServer Pages, Java Expression Language, and Java WebSocket technologies. The issue lies within the Apache Tomcat installer for Windows<\/a>. During the installation process, the installer uses icacls.exe without specifying a full path. This behavior leads to an untrusted search path vulnerability<\/a>, potentially allowing an attacker to escalate their privileges and compromise the system or leak data.
\nGiven the widespread use of Apache Tomcat and its critical role in many web applications, this vulnerability could potentially<\/a> impact a wide range of users and organizations. It is, therefore, of utmost importance to understand the implications of this vulnerability<\/a> and how to mitigate it.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-49124
\nSeverity: High (8.4 CVSS Severity Score)
\nAttack Vector: Local
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Apache Tomcat | 11.0.0-M1 through 11.0.7
\nApache Tomcat | 10.1.0 through 10.1.41
\nApache Tomcat | 9.0.23 through 9.0.105<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from the Apache Tomcat installer<\/a> for Windows using icacls.exe without specifying a full path. This leads to an untrusted search path vulnerability<\/a>, where the system might execute a malicious binary placed by an attacker in the search path. The attacker could potentially exploit<\/a> this to elevate privileges, compromising the system or leading to data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

While no specific exploit code is currently known for this vulnerability<\/a>, an attacker could potentially exploit this vulnerability using a similar approach to the following:<\/p>\n

REM Place a malicious binary named icacls.exe in a location in PATH\necho \"malicious code\" > C:\\some\\path\\in\\PATH\\icacls.exe\nREM Trigger the Apache Tomcat installation process\nstart \/wait C:\\path\\to\\apache-tomcat-installer.exe<\/code><\/pre>\n
In this scenario, when the Apache Tomcat installer attempts to execute icacls.exe, it could inadvertently execute the malicious binary placed by the attacker, leading to potential system<\/a> compromise or data leakage.<\/p>\n","protected":false},"excerpt":{"rendered":"
