Summary
A security regression of CVE-2019-9636 was discovered in Python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1. An attacker can still exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other information, it is possible for an attacker to provide specially crafted URLs to make the application send host-related information to a different host than intended.
Risk Assessment
Risk of leaking cookies and authentication data to incorrect hosts, potentially leading to session theft or credential compromise.
Recommendation
Upgrade Python to version 2.7.17, 3.5.10, 3.6.10, 3.7.3 or later, and if using 3.8, upgrade to 3.8.0b2 or later.
Other vulnerabilities in Python
See all- CVE-2013-7338High
Python versions before 3.3.4 RC1 allow remote attackers to cause a denial of service via a file size value larger than the size of the zip file in functions related to reading and extracting zip files.
- CVE-2022-42919High
A vulnerability in Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The multiprocessing library with the forkserver start method permits pickle deserialization from any user on the same local network of the machine.
- CVE-2026-1299Medium
The email module in Python, specifically the BytesGenerator class, improperly quotes newlines in email headers during serialization, allowing header injection. This only affects usage of LiteralHeader that does not respect email folding.
- CVE-2023-27043Medium
The email module in Python through 3.11.3 incorrectly parses email addresses containing special characters. The wrong portion of an RFC2822 header is identified as the value of the addr-spec.
- CVE-2023-24329High
A vulnerability in the urllib.parse component of Python before version 3.11.4 allows attackers to bypass blocklisting methods by supplying a URL that starts with blank characters.
- CVE-2020-10735High
A flaw was found in Python. In algorithms with quadratic time complexity using non-binary bases, when using int("text"), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability.
- CVE-2021-3737High
A flaw in Python's HTTP client code, when improperly handling an HTTP response, may cause the client script to enter an infinite loop, consuming CPU time. The highest threat is to system availability.
- CVE-2022-0391High
A flaw in Python's urllib.parse module, where the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path, enabling an attacker to craft a URL that leads to injection attacks. Affected versions are earlier than 3.10.0b1, 3.9.5, 3.8.11, 3.7.11, and 3.6.14.
- CVE-2021-29921Critical
In Python before 3.9.5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This (in some situations) allows attackers to bypass access control that is based on IP addresses.
- CVE-2021-23336Medium
The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server.
Original NVD description (English source)
A security regression of CVE-2019-9636 was discovered in python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.
