Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU35713

Risk: High

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2020-11984

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in od_proxy_uwsgi module. A remote attacker can send a specially crafted request to the web server, trigger memory corruption and gain access to sensitive information or execute arbitrary code on the target system.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 31

httpd: before 2.4.46-1.fc31

CPE2.3 External links

https://bodhi.fedoraproject.org/updates/FEDORA-2020-0d3d3f5072


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: #VU26527

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-2020-1927

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 some "mod_rewrite" configurations. 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) Use of Uninitialized Variable

EUVDB-ID: #VU26528

Risk: Medium

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

CVE-ID: CVE-2020-1934

CWE-ID: CWE-457 - Use of Uninitialized Variable

Exploit availability: No

Description

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

The vulnerability exists due to the "mod_proxy_ftp" may use uninitialized memory when proxying to a malicious FTP server. A remote attacker can gain unauthorized access to sensitive information on the target system.

Mitigation

Install updates from vendor's repository.

4) Input validation error

EUVDB-ID: #VU35776

Risk: Medium

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

CVE-ID: CVE-2020-11985

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a spoofing attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can spoof the user's IP address when proxying using mod_remoteip and mod_rewrite, as a result the fake IP address will be displayed in logs and will be passed to PHP scripts.

Depending on web application functionality this vulnerability can be used to bypass authorization checks based on IP addresses.

Mitigation

Install updates from vendor's repository.
