Arbitrary Code Execution in Cookie Serialization

CVE-2017-1000053 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

The default serialization used by Plug session may result in code execution
in certain situations. Keep in mind, however, the session cookie is signed
and this attack can only be exploited if the attacker has access to your
secret key as well as your signing/encryption salts. We recommend users to
change their secret key base and salts if they suspect they have been leaked,
regardless of this vulnerability.

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:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
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.
