Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Type conversion

EUVDB-ID: #VU67760

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-10735

CWE-ID: CWE-704 - Type conversion

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's repository.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Open redirect

EUVDB-ID: #VU67591

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-28861

CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's repository.

3) Resource exhaustion

EUVDB-ID: #VU69392

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-45061

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's repository.
