CVE intelligence and bounded remediation
CVE-2019-14251 — An issue was discovered in T24 in TEMENOS Channels R15.01
An issue was discovered in T24 in TEMENOS Channels R15.01. The login page presents JavaScript functions to access a document on the server once successfully authenticated. However, an attacker can leverage downloadDocServer() to traverse the file system and access files or directories that are outside of the restricted directory because WealthT24/GetImage is used with the docDownloadPath and uploadLocation parameters.

Matched remediation archetype
Path traversal, unsafe upload, and file handling
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
- Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
- Review canonicalization and containment checks across supported operating systems and storage backends.
Remediate safely
- Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
- Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
- Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
