CVE-2020-5026

Vulnerability

IBM Financial Transaction Manager for Digital Payments for Multi-Platform versions 3.2.0 through 3.2.7 contain a vulnerability (CVE-2020-5026) where the application returns detailed technical error messages directly in the browser. This behavior can expose sensitive system information to a remote attacker who triggers an error condition [1].

Exploitation

An unauthenticated remote attacker can send specially crafted requests to the affected application that cause detailed error messages to be displayed. No special privileges or user interaction are required beyond network access. The attacker can then read the contents of the error page, which may include database queries, file paths, or system configuration details [1].

Impact

Successful exploitation allows the attacker to obtain sensitive information about the underlying system, database, or application internals. This information disclosure can be used to plan and execute further attacks against the same infrastructure, potentially leading to broader compromise [1].

Mitigation

IBM has released a fix as part of a larger remediation. Users should upgrade to version 3.2.7.1 or later, as specified in the vendor advisory. In the absence of a patch, administrators can limit error verbosity through application server settings or web server error handling to prevent detailed technical messages from being returned to the client [1].
