Authenticated file disclosure via unchecked download path
Published Feb 18, 2026 · Updated Feb 18, 2026
Path traversal in Tsinghua Unigroup Electronic Archives System 3.2.210802(62532) allows remote authenticated users to read server files. The /Using/Subject/downLoad.html handler uses the unvalidated path argument to resolve a download outside its intended directory. Exploitation requires a low-privileged authenticated session; the demonstrated consequence is confidentiality-only file disclosure.
