Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Improper Authentication (CVE-ID: CVE-2021-21994)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests in SFCB (Small Footprint CIM Broker). A remote attacker can send specially crafted requests to port 5989/tcp, bypass SFCB authentication and gain unauthorized access to the system.


2) Out-of-bounds read (CVE-ID: CVE-2021-21995)

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

The vulnerability exists due to a boundary condition when processing requests within the OpenSLP service. A remote attacker can send a specially crafted request to port 427/UDP, trigger a heap out-of-bounds read and perform a denial of service attack.


3) Information disclosure (CVE-ID: CVE-2020-24511)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to improper isolation of shared resources. A local user can gain unauthorized access to sensitive information on the system.


4) Improper Initialization (CVE-ID: CVE-2020-12357)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper initialization in the firmware. A local administrator can run a specially crafted application to execute arbitrary code with escalated privileges on the system.


5) Buffer overflow (CVE-ID: CVE-2020-12358)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error when in the firmware. A local administrator can trigger memory corruption and cause a denial of service condition on the target system.


6) Out-of-bounds read (CVE-ID: CVE-2020-12360)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in the firmware. A local user can trigger out-of-bounds read error and read contents of memory on the system.


7) Input validation error (CVE-ID: CVE-2020-24486)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the firmware. A local user can pass specially crafted input to the application and perform a denial of service (DoS) attack.


8) Open redirect (CVE-ID: CVE-2021-21579)

The vulnerability allows a remote attacker to redirect victims to arbitrary URL.

The vulnerability exists due to improper sanitization of user-supplied data. 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.


9) Open redirect (CVE-ID: CVE-2021-21578)

The vulnerability allows a remote attacker to redirect victims to arbitrary URL.

The vulnerability exists due to improper sanitization of user-supplied data. 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.


10) Cross-site scripting (CVE-ID: CVE-2021-21577)

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. 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.


11) Cross-site scripting (CVE-ID: CVE-2021-21576)

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. 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.
