Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Cross-site scripting

EUVDB-ID: #VU18296

Risk: Medium

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:Green]

CVE-ID: CVE-2019-10909

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 perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data within the form theme of the PHP templating engine. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in 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.

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) Code injection

EUVDB-ID: #VU18297

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-2019-10910

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to insufficient sanitization of user-supplied data related to service identifiers. A remote attacker can send specially crafted HTTP request to the affected system and execute arbitrary PHP code.

Successful exploitation of this vulnerability may allow a remote attacker to compromise the affected application.

Mitigation

Install updates from vendor's repository.

3) Improper authentication

EUVDB-ID: #VU18298

Risk: Medium

CVSSv4.0: 5.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-10911

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to the way application handles values within HTTP cookies, related to session expiration time and username. A remote attacker can modify the remember me cookie value and authenticate as a different user.

This attack is only possible if remember me functionality is enabled and the two users share a password hash or the password hashes (e.g. UserInterface::getPassword()) are null for all users (which is valid if passwords are checked by an external system, e.g. an SSO).

Mitigation

Install updates from vendor's repository.

4) Prototype pollution

EUVDB-ID: #VU18092

Risk: Low

CVSSv4.0: 5.5 [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:P/U:Clear]

CVE-ID: CVE-2019-11358
