CVE-2024-12642 | Chunghwa Telecom TenderDocTransfer - Arbitrary File Write

TenderDocTransfer from Chunghwa Telecom has an Arbitrary File Write vulnerability. The application sets up a simple local web server and provides APIs for communication with the target website.

Additionally, one of the APIs contains a Relative Path Traversal vulnerability, allowing attackers to write arbitrary files to any path on the user's system.

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.

A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
