CVE-2025-55754: 
Java vulnerability analysis and mitigation

CVE-2025-55754 is a security vulnerability discovered in Apache Tomcat related to improper neutralization of ANSI escape sequences in log messages. The vulnerability was disclosed on October 27, 2025, affecting multiple versions of Apache Tomcat including 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, as well as EOL versions 8.5.60 through 8.5.100 (NVD Database, Security Online).

The vulnerability stems from Tomcat's failure to properly escape ANSI escape sequences in log messages. It is classified under CWE-150 (Improper Neutralization of Escape, Meta, or Control Sequences). The issue specifically affects instances where Tomcat is running in a console on Windows operating systems that support ANSI escape sequences. Through this vulnerability, attackers can potentially inject ANSI escape sequences via specially crafted URLs (NVD Database).

When exploited, this vulnerability allows attackers to manipulate the console display and clipboard content, potentially tricking administrators into executing attacker-controlled commands. While the primary attack vector has been identified on Windows systems, Apache has noted that similar attacks might be possible on other operating systems (Cybersecurity News).

Users are strongly recommended to upgrade to the patched versions: Tomcat 11.0.11 or later, 10.1.45 or later, or 9.0.109 or later, which include fixes for this vulnerability. These updates implement proper escaping of ANSI sequences in log messages to prevent potential exploitation (NVD Database).
