Description

This security bulletin contains information about 5 vulnerabilities.


1) Code injection (CVE-ID: CVE-2019-10910)

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

CVSSv4: 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


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.

2) Cross-site scripting (CVE-ID: CVE-2019-10909)

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

CVSSv4: 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


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.


3) Insecure deserialization (CVE-ID: CVE-2019-10912)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

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


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

The vulnerability exists due to insecure call of the unserialize() PHP function in untrusted user-input. A remote attacker can send specially crafted HTTP request to the affected system and delete arbitrary files on the system or display raw data output.


4) Improper authentication (CVE-ID: CVE-2019-10911)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: 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


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).

5) Improper input validation (CVE-ID: CVE-2019-10913)

CWE-ID: CWE-20 - Improper input validation

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


The disclosed vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to absent validation of HTTP methods when processing methods directly or via X-Http-Method-Override header. A remote attacker can pass specially crafted string as HTTP method and bypass certain security restrictions.
