What is CVE-2024-53256?
CVE-2024-53256 is a high-severity command injection vulnerability in rizinorg rizin, published on 23 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Rizin is a UNIX-like reverse engineering framework and command-line toolset. `rizin.c` still had an old snippet of code which suffered a command injection due the usage of `rz_core_cmdf` to invoke the command `m` which was removed in v0.1.x. A malicious binary defining `bclass` (part of RzBinInfo) is executed if `rclass` (part of RzBinInfo) is set to `fs`; the vulnerability can be exploited by any bin format where `bclass` and `rclass` are user defined. This vulnerability is fixed in 0.7.4.
Weakness: CWE-78
