CVE-2022-28391 is a high-severity vulnerability affecting BusyBox versions up to 1.35.0. This vulnerability allows remote attackers to execute arbitrary code if the 'netstat' command is utilized to print a DNS PTR record's value to a VT compatible terminal. In an alternative scenario, attackers could modify the terminal's colors. The CVSS score for this vulnerability is 8.8, indicating a high level of risk due to its potential impact on systems.
The vulnerability's exploitation could lead to significant consequences, including unauthorized access and control over affected systems. As a result, organizations using BusyBox should treat this issue with urgency, especially given the network attack vector and the low complexity of the attack.
Currently, there are no known public exploits for CVE-2022-28391, but the potential for exploitation remains. Organizations should prioritize patching immediately to secure their systems against this vulnerability.
Given the high CVSS score and the significant potential impact, it is imperative for organizations to assess their deployment of BusyBox and take appropriate action to mitigate any associated risks.
Vulnerability Details
The official description of CVE-2022-28391 states that "BusyBox through 1.35.0 allows remote attackers to execute arbitrary code if netstat is used to print a DNS PTR record's value to a VT compatible terminal. Alternatively, the attacker could choose to change the terminal's colors." This vulnerability is classified under CWE-88, indicating an improper argument. The CVSS score is set at 8.8, denoting a high severity level.
The affected product is BusyBox, and the vulnerability was published on April 3, 2022. This high-severity vulnerability necessitates immediate attention from security teams to implement necessary patches.
Technical Analysis
The root cause of CVE-2022-28391 lies in the handling of data by the BusyBox's 'netstat' command, which can lead to the execution of arbitrary code when certain conditions are met. The attack vector is classified as network-based, meaning that an attacker can exploit the vulnerability remotely. The attack complexity is low, requiring minimal skill or resources for successful exploitation.
No privileges are required for the attack to be successful, and user interaction is necessary as the victim must invoke the vulnerable command. If successfully exploited, the impact on confidentiality, integrity, and availability is high, highlighting the critical nature of this vulnerability.
Risk & Impact Analysis
The real-world risk presented by CVE-2022-28391 is significant, given that BusyBox is commonly used in various embedded systems and servers. The potential for an attacker to execute arbitrary code remotely could lead to unauthorized access and control over critical systems, making this a high-priority issue for organizations.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The urgency is underscored by the high CVSS score, indicating the need for swift action to protect systems from exploitation.
