Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Cross-site scripting in Django

EUVDB-ID: #VU165

Risk: High

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:P/U:Amber]

CVE-ID: CVE-2016-6186

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to improper filtering HTML code from user-supplied input. A remote user can cause arbitrary scripting code execution by the target administrative user's browser. The code will originate from the site running the Django software. As a result, the code will be able to access the target user's cookies, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 7

python-django16: before 1.6.11.7-5.el7

python-django: before 1.11.13-4.el7

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. However, proof of concept for this vulnerability is available.

2) Cross-site scripting

EUVDB-ID: #VU7105

Risk: Low

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

CVE-ID: CVE-2017-7233

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to redirect website visitors to external websites and perform cross-site scripting (XSS) attacks.

The vulnerability is caused by incorrect filtration of input data. A remote attacker can trick the victim to follow a specially crafted link, redirect the victim on potentially dangerous website and execute arbitrary HTML and script code in victim’s browser in security context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Is there known malware, which exploits this vulnerability?

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

3) Improper input validation

EUVDB-ID: #VU10952

Risk: Low

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:Clear]

CVE-ID: CVE-2018-7536

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the django.utils.html.urlize() function due to insufficient validation of user-supplied input. A remote attacker can submit a specially crafted input and cause the service to crash.

Mitigation

Install updates from vendor's repository.

4) Resource exhaustion

EUVDB-ID: #VU11476

Risk: Low

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:Clear]

CVE-ID: CVE-2018-7537

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the django.utils.html.urlize() function due to it was extremely slow to evaluate certain inputs due to catastrophic backtracking vulnerabilities in two regular expressions. The urlize() function is used to implement the urlize and urlizetrunc template filters, which were thus vulnerable. A remote attacker can cause the service to crash.

Mitigation

Install updates from vendor's repository.

5) Open redirect

EUVDB-ID: #VU14175

Risk: Low

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:Clear]

CVE-ID: CVE-2018-14574

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

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to redirect the target user to external websites.

The weakness exists on systems with django.middleware.common.CommonMiddleware and the APPEND_SLASH setting enabled and with a project that has a URL pattern that accepts any path ending in a slash due to open redirect. A remote attacker can use a specially crafted image link, trick the victim into opening it and redirect users to malicious website

Mitigation

Install updates from vendor's repository.
