LFI in PHP-Proxy 5.1.0

Description

PHP-Proxy 5.1.0 allows remote attackers to read local files if the default "pre-installed version" (intended for users who lack shell access to their web server) is used. This occurs because the aeb067ca0aa9a3193dce3a7264c90187 app_key value from the default config.php is in place, and this value can be easily used to calculate the authorization data needed for local file inclusion.

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:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
