CVE-2024-21733
Description
An information disclosure vulnerability was found in Apache Tomcat. Incomplete POST requests triggered an error response that could contain data from a previous HTTP request. This flaw allows a remote attacker to access files from another user that should be otherwise prevented by limits or authentication.
Statement
Red Hat Enterprise Linux remains unaffected as the vulnerable version of Tomcat (e.g., versions 8.5.7 through 8.5.63 and 9.0.0 through 9.0.43) has not been shipped or included.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Often this will either reveal sensitive information which may be used to launch another, more focused attack or disclose private information stored in the server. For example, an attempt to exploit a path traversal weakness (CWE-22) might yield the full pathname of the installed application. In turn, this could be used to select the proper number of ".." sequences to navigate to the targeted file. An attack using SQL injection (CWE-89) might not initially succeed, but an error message could reveal the malformed query, which would expose query logic and possibly even passwords or other sensitive information used within the query.
