Risk: High
CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2020-8252
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to incorrect validation of realpath in libuv. The library incorrectly determines the buffer size, which can result in a buffer overflow if the resolved path is longer than 256 bytes. A remote attacker can pass an overly long path to the application that is using the library, trigger memory corruption and execute arbitrary code on the system.
