EUVDB-ID: #VU19256
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-20852
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the "http.cookiejar.DefaultPolicy.domain_return_ok" in the "Lib/http/cookiejar.py" file returns incorrect results during cookie domain checks. A remote attacker can trick a victim to execute a program that uses the "http.cookiejar.DefaultPolicy" to make an HTTP connection to an attacker-controlled server with a hostname that has another valid hostname as a suffix.
Successful exploitation of this vulnerability can allow an attacker to gain unauthorized access to sensitive information on the system, such as existing cookies. Mitigation
