CVE-2024-42640

Exp

angular-base64-upload prior to v0.1.21 is vulnerable to unauthenticated remote code execution via demo/server.php. Exploiting this vulnerability allows an attacker to upload arbitrary content to the server, which can subsequently be accessed through demo/uploads. This leads to the execution of previously uploaded content and enables the attacker to achieve code execution on the server. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

9.8 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
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.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
