Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Origin validation error

EUVDB-ID: #VU61611

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-21712

CWE-ID: CWE-346 - Origin Validation Error

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to origin validation error in the "twited.web.RedirectAgent" and "twisted.web.BrowserLikeRedirectAgent" functions. A remote attacker attacker can trick the victim to click on a specially crafted link and obtain cookies and authorization headers.

Mitigation

Update the affected packages:

noarch:
    python3-twisted+tls-22.4.0-124.amzn2023.0.2.noarch
    python3-twisted-22.4.0-124.amzn2023.0.2.noarch

src:
    python-twisted-22.4.0-124.amzn2023.0.2.src

Vulnerable software versions

Amazon Linux AMI: All versions

python-twisted: before 22.4.0-124

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) Buffer overflow

EUVDB-ID: #VU61017

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-2022-21716

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error. A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.

Mitigation

Update the affected packages:

noarch:
    python3-twisted+tls-22.4.0-124.amzn2023.0.2.noarch
    python3-twisted-22.4.0-124.amzn2023.0.2.noarch

src:
    python-twisted-22.4.0-124.amzn2023.0.2.src

Vulnerable software versions

Amazon Linux AMI: All versions

python-twisted: before 22.4.0-124

3) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU62077

Risk: Medium

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-24801

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

Exploit availability: No

Description

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests within the twisted.web.http module. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

Mitigation

Update the affected packages:

noarch:
    python3-twisted+tls-22.4.0-124.amzn2023.0.2.noarch
    python3-twisted-22.4.0-124.amzn2023.0.2.noarch
