Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-55754 involves an improper neutralization of ANSI escape sequences in Apache Tomcat log messages. If Tomcat is running in a console on a Windows operating system that supports ANSI escape sequences, a remote attacker could inject ANSI escape sequences by using a specially crafted URL. These injected sequences could then be used to manipulate the console display and clipboard, potentially tricking a system administrator into executing attacker-controlled commands. While no specific attack vector has been identified, it may be possible to mount this attack on other operating systems. This affects Apache Tomcat versions 11.0.0-M1 through 11.0.10, 10.1.0-M1 through 10.1.44, and 9.0.40 through 9.0.108. It is recommended to upgrade to version 11.0.11 or later, 10.1.45 or later, or 9.0.109 or later.

Description: Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat. Tomcat did not escape ANSI escape sequences in log messages. If Tomcat was running in a console on a Windows operating system, and the console supported ANSI escape sequences, it was possible for an attacker to use a specially crafted URL to inject ANSI escape sequences to manipulate the console and the clipboard and attempt to trick an administrator into running an attacker controlled command. While no attack vector was found, it may have been possible to mount this attack on other operating systems. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.10, from 10.1.0-M1 through 10.1.44, from 9.0.40 through 9.0.108. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.60 though 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.11 or later, 10.1.45 or later or 9.0.109 or later, which fix the issue.
