Authenticated arbitrary file read and modification via traversal
Published May 26, 2023 · Updated Jan 15, 2025
Directory traversal in Encourage Technologies ESS REC Agent Server Edition allows authenticated attackers to view or alter arbitrary server files. The public JVN advisory does not disclose the affected handler or the path-validation operation that accepts traversal sequences. The authenticated attacker must have local low-privileged access; successful exploitation permits arbitrary file disclosure or modification.
