CVE-2018-9919

Exp

A web-accessible backdoor, with resultant SSRF, exists in Tp-shop 2.0.5 through 2.0.8, which allows remote attackers to obtain sensitive information, attack intranet hosts, or possibly trigger remote command execution, because /vendor/phpdocumentor/reflection-docblock/tests/phpDocumentor/Reflection/DocBlock/Tag/LinkTagTeet.php writes data from the "down_url" URL into the "bddlj" local file if the attacker knows the backdoor "jmmy" parameter.

Base score Version Severity Vector Exploitability Impact Score source
9.8 3.0 CRITICAL
CVSS:3.0/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.
