2) Information disclosure
EUVDB-ID: #VU19256
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
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
