Improper Control of Generation of Code ('Code Injection') in jai-ext

CVE-2022-24816 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

Programs using jt-jiffle, and allowing Jiffle script to be provided via network request, are susceptible to a Remote Code Execution as the Jiffle script is compiled into Java code via Janino, and executed. In particular, this affects the downstream GeoServer project.

Patches

Version 1.2.22 will contain a patch that disables the ability to inject malicious code into the resulting script.

Workarounds

Negate the ability to compile Jiffle scripts from the final application, by removing janino-x.y.z.jar from the classpath.

References

None.

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.
Exploit maturity (E:H)
Exploits are easy to find or already weaponized—assume people are using them.
