Ivanti ICS: Critical Command Injection and High Authentication Bypass Vulnerabilities

What are the CVE-2024-21887 and CVE-2023-46805 Vulnerabilities in Ivanti ICS?

Ivanti Connect Secure (ICS), previously known as Pulse Connect Secure and Ivanti Policy Secure gateways, faces two significant vulnerabilities: CVE-2024-21887 and CVE-2023-46805. The first, a command injection vulnerability with a CVSS score of 9.1, allows unauthorized remote execution via a file upload function flaw. This vulnerability affects versions 9.x and 22.x. The second, CVE-2023-46805, is an authentication bypass vulnerability, rated high severity with a CVSS score of 8.2, stemming from a flaw in the authorization function. These vulnerabilities can lead to full remote server control, data theft, and malware execution.

Why Should TPRM Professionals Pay Attention to These Ivanti ICS Vulnerabilities?

These vulnerabilities are critical for TPRM professionals to monitor. They pose significant risks including unauthorized remote control, data theft, and potential participation in malicious activities like botnet joining or malware distribution. Furthermore, the exploitation of these vulnerabilities by a Chinese nation-state level threat actor, UTA0178, underscores their severity.

Key Questions for Vendors Regarding Ivanti ICS Vulnerabilities

TPRM professionals should ask vendors specific questions:

  1. Have you assessed your systems for the presence of Ivanti Connect Secure versions 9.x and 22.x?
  2. What measures are in place to detect and mitigate unauthorized access or command execution via these vulnerabilities?
  3. Can you provide a timeline for patching these vulnerabilities in your systems?
  4. How are you monitoring for potential exploitation or suspicious activities related to these vulnerabilities?

Cacti SQLi: High-Risk Blind SQL Injection Vulnerability

What is the CVE-2023-51448 Vulnerability in Cacti?

CVE-2023-51448 is a high-severity Blind SQL Injection (SQLi) vulnerability in Cacti, specifically affecting version 1.2.25. It has a CVSS score of 8.8 and an EPSS probability of 0.071%. This vulnerability allows an authenticated attacker with ‘Settings/Utilities’ permission to execute arbitrary SQL commands on the Cacti database. It was first reported by Synopsys CyRC researcher Matthew Hogg. The vulnerability occurs due to unsanitized input in the ‘selected_graphs_array’ parameter of a GET request, leading to potential disclosure of sensitive database contents and other severe impacts.

Why Should TPRM Professionals Be Concerned About CVE-2023-51448?

This vulnerability poses a significant risk for unauthorized data access and manipulation within the Cacti monitoring tool. TPRM professionals must be vigilant, as the exploitation of this flaw could lead to sensitive data theft, unauthorized modification of user accounts or configurations, and even potential arbitrary code execution, depending on the database setup.

Essential Questions for Vendors Regarding CVE-2023-51448

TPRM professionals should query vendors with specific concerns:

  1. Have you identified the use of Cacti version 1.2.25 within your network?
  2. What measures have you implemented to prevent unauthorized SQL command execution through this vulnerability?
  3. Can you detail your upgrade plans to patch this vulnerability?
  4. How do you monitor and detect any potential exploitation attempts related to CVE-2023-51448?

Remediation Recommendations for Affected Vendors

Vendors should:

  • Upgrade to Cacti version 1.2.26 or later, which addresses this vulnerability.
  • Limit access to the ‘Settings/Utilities’ permission required for exploiting this flaw.
  • Enforce strong password policies to reduce the risk of unauthorized access.
  • Continuously monitor network activities for signs of exploitation or unusual changes.

What are CVE-2023-0656 and CVE-2022-22274 in SonicWall SonicOS?

SonicWall SonicOS faces two significant vulnerabilities: CVE-2023-0656 and CVE-2022-22274. Both are stack-based buffer overflow vulnerabilities, with CVE-2023-0656 rated as high (CVSS: 7.5, EPSS: 0.115%) and CVE-2022-22274 as critical (CVSS: 9.8, EPSS: 0.366%). CVE-2023-0656 allows a remote unauthenticated attacker to cause a Denial of Service (DoS), potentially crashing the firewall. CVE-2022-22274, on the other hand, not only poses a DoS threat but also allows for potential remote code execution (RCE), enabling an attacker to take control of the affected device. These vulnerabilities primarily impact the web management interface of SonicWall firewalls.

Why Should TPRM Professionals Be Concerned About These SonicWall SonicOS Vulnerabilities?

These vulnerabilities are crucial for TPRM professionals due to their potential impact on network security. The risks include DoS attacks, which could disrupt critical business operations, and RCE, which could lead to data theft, unauthorized system control, and further malicious activities. With over 178,000 SonicWall firewalls potentially exposed, the scope of these vulnerabilities is significant.

Key Questions for Vendors Regarding SonicWall SonicOS Vulnerabilities

TPRM professionals should inquire with vendors about:

  1. Confirmation of the use of SonicWall SonicOS in their infrastructure and the versions in use.
  2. Steps taken to patch or mitigate the vulnerabilities, especially in light of their severity.
  3. Strategies in place to detect and respond to potential exploitation attempts.
  4. The status of their network security in relation to the SonicWall vulnerabilities, including any incident response plans.

Remediation Recommendations for Vendors

Vendors should:

  • Update SonicWall Firewall to the fixed version.
  • Restrict access to the web management interface to mitigate risks.
  • Use a firewall or antivirus program to provide additional layers of security.
  • Regularly review and update security settings to prevent exploitation.
  • Monitor network traffic for signs of unusual activities or potential attacks.

Confluence Data Center and Server: Critical and High Template Injection Vulnerabilities

What are CVE-2023-22527 and CVE-2023-22522 in Confluence Data Center and Server?

Confluence Data Center and Server have been identified with two severe vulnerabilities: CVE-2023-22527 and CVE-2023-22522. CVE-2023-22527, a critical vulnerability (CVSS: 10), involves template injection leading to Remote Code Execution (RCE). It allows unauthenticated attackers to execute arbitrary code on affected instances. CVE-2023-22522, a high-severity vulnerability (CVSS: 8.8, EPSS: 0.11%), also involves RCE through template injection. These vulnerabilities are particularly dangerous because they enable attackers to gain access to and modify system files, compromise user accounts, distribute ransomware, and utilize a botnet.

Why Should TPRM Professionals Be Concerned About These Confluence Vulnerabilities?

The critical nature of these vulnerabilities, especially their potential for RCE, makes them a significant concern for TPRM professionals. The vulnerabilities can lead to severe consequences, including data breaches, system compromise, and the spread of malware. Given the widespread use of Confluence in enterprise environments, the impact could be extensive and damaging.
