Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Off-by-one (CVE-ID: CVE-2021-46848)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an ETYPE_OK off-by-one error in asn1_encode_simple_der in Libtasn1. A remote attacker can pass specially crafted data to the application, trigger an off-by-one error and perform a denial of service (DoS) attack.
2) Type conversion (CVE-ID: CVE-2020-10735)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion in algorithms with quadratic time complexity when using non-binary bases within the int() call. A remote attacker can pass specially crafted data to the affected application and perform a denial of service (DoS) attack.
3) Open redirect (CVE-ID: CVE-2021-28861)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data in lib/http/server.py due to missing protection against multiple (/) at the beginning of URI path. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
4) Resource exhaustion (CVE-ID: CVE-2022-45061)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to usage of an unnecessary quadratic algorithm in one path when processing some inputs to the IDNA (RFC 3490) decoder. A remote attacker can pass a specially crafted name to he decoder, trigger resource excessive CPU consumption and perform a denial of service (DoS) attack.
5) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-24998)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to Apache Commons FileUpload does not limit the number of request parts. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.
6) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-25927)
The vulnerability allows a remote user to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests. A remote user can send a specially crafted HTTP request to the server resulting in loss of access to the system.
