Deserialization of Untrusted Data


Severity High
Score 9.8/10


** DISPUTED ** pandas can unserialize and execute commands from an untrusted file that is passed to the "read_pickle()" function, if "__reduce__" makes an "os.system call". NOTE: third parties dispute this issue because the "read_pickle()" function is documented as unsafe and it is the user's responsibility to use the function in a secure manner.

CWE-502 - Deserialization of Untrusted Data

Deserialization of untrusted data vulnerabilities enable an attacker to replace or manipulate a serialized object, replacing it with malicious data. When the object is deserialized at the victim's end the malicious data is able to compromise the victim’s system. The exploit can be devastating, its impact may range from privilege escalation, broken access control, or denial of service attacks to allowing unauthorized access to the application's internal code and logic which can compromise the entire system.
