CVE-2022-0585 identifies a vulnerability within Wireshark, a widely used network protocol analyzer. This vulnerability allows denial of service due to large loops present in multiple protocol dissectors in versions 3.6.0 to 3.6.1 and 3.4.0 to 3.4.11 of Wireshark. Attackers can exploit this flaw through packet injection or by using a crafted capture file, which may lead to significant disruptions in service.
The vulnerability has been assigned a CVSS score of 4.3, categorizing it as medium severity. The impact includes a low availability score, indicating that while the confidentiality and integrity of data are not compromised, the availability of the service can be significantly affected. Organizations operating with the affected versions of Wireshark must be aware of the potential risks and the urgency of addressing this issue.
Given the nature of the vulnerability and its exploitation method, organizations should prioritize patching immediately. The risk to organizations includes potential service disruptions and the associated impact on network operations.
As of now, there are no known exploits available in the wild, and the vulnerability is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant and monitor for any updates regarding this vulnerability.
Organizations are encouraged to review their deployments of Wireshark and apply necessary patches to mitigate this vulnerability effectively.
Vulnerability Details
According to the official CVE description, this vulnerability allows denial of service via packet injection or crafted capture files. The CVSS score variations indicate a medium severity level, reflecting the impact on availability primarily. The affected versions include Wireshark versions 3.6.0 to 3.6.1 and 3.4.0 to 3.4.11.
The vulnerability is classified under CWE-834, indicating improper handling of large loops in protocol dissectors, which can lead to service interruptions.
Technical Analysis
The root cause of CVE-2022-0585 stems from inefficient handling of packets in protocol dissectors. The attack vector is network-based, enabling attackers to exploit this vulnerability remotely. The attack complexity is rated as low, meaning that minimal effort is required to execute an attack successfully.
No privileges are required to exploit this vulnerability, but user interaction is necessary for an attacker to succeed. This affects availability since an attacker can disrupt service by sending crafted packets or files, causing large loops in the dissectors.
The vulnerability does not impact confidentiality or integrity, but it can severely impair the availability of the affected systems, leading to potential service outages.
Risk & Impact Analysis
Real-world deployment of Wireshark with this vulnerability can lead to substantial consequences, particularly in environments dependent on reliable network analysis tools. The blast radius can be significant, affecting all users of the affected Wireshark versions and potentially resulting in widespread denial of service.
Given that the CVSS score is classified as medium, organizations should address this vulnerability in their priority patch cycle. The risk to organizations includes service disruptions that can affect operations, leading to financial and reputational damage.

Affected Versions
The affected versions of Wireshark include 3.6.0 to 3.6.1 and 3.4.0 to 3.4.11. Organizations should ensure they are running versions beyond 3.4.11 or 3.6.1 to mitigate this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching affected versions of Wireshark as outlined in the vendor advisory. The recommended action is to upgrade to the latest versions beyond the affected range. If immediate patching is not feasible, consider implementing network controls to limit exposure to potentially crafted packets.
Configuration hardening should also be reviewed to minimize risks associated with packet processing. Monitoring network traffic for unusual patterns may help in detecting potential exploitation attempts.
Continuous security testing can also assist in validating remediation efforts and uncovering additional vulnerabilities.
Detection Guidance
Monitoring for behavioral anomalies in traffic patterns could provide early indications of exploitation attempts. Log analysis should be performed regularly to identify unusual packet injections or malformed capture files that could exploit this vulnerability.
AppSecure Threat Intelligence Insight
