CVE-2022-30630 is a high-severity vulnerability classified with a CVSS score of 7.5. This vulnerability allows an attacker to exploit uncontrolled recursion in the Glob function within the io/fs package of Golang, leading to stack exhaustion. The issue affects all versions prior to Go 1.17.12 and 1.18.4. Organizations using these versions are at risk, as attackers may leverage this vulnerability to cause a panic in the application.
The real-world risk context of this vulnerability is significant. If exploited, it can lead to application downtime due to stack exhaustion, impacting the availability of services. Given the low complexity of the attack and the fact that no privileges or user interaction are required, organizations should prioritize patching immediately. The exposure of this vulnerability on the network means that it is easily exploitable from external sources.
As of the latest updates, there are no known public exploits for CVE-2022-30630, but the potential for exploitation exists. Organizations should be vigilant and ensure that their systems are updated to the latest versions of Go to mitigate this risk. Patching should be treated as a priority to prevent possible disruptions.
In summary, CVE-2022-30630 poses a high risk to organizations utilizing affected versions of Golang. Immediate action is required to address this vulnerability and secure systems against potential exploitation.
Vulnerability Details
The vulnerability is due to uncontrolled recursion in the Glob function found in the io/fs package of Golang. Specifically, it allows an attacker to cause a panic due to stack exhaustion via a path containing a large number of path separators. The affected versions are all prior to Go 1.17.12 and Go 1.18.4.
The CVSS score for this vulnerability is 7.5, indicating a high severity level. The attack vector is categorized as NETWORK with low complexity and no privileges or user interaction required. The availability impact is high, while confidentiality and integrity impacts are noted as none.
Technical Analysis
The root cause of CVE-2022-30630 lies in the design of the Glob function, where recursion can be triggered by malicious input. The attack vector is network-based, meaning that an attacker can exploit the vulnerability remotely. The complexity of executing the attack is low, and it requires no special privileges or user interaction.
The impacts of this vulnerability are especially concerning regarding availability. If exploited, the application may crash, leading to service disruptions. Organizations using affected versions should assess their exposure and implement appropriate safeguards.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses significant risk to organizations. The potential for service disruption is high, especially for applications reliant on the Glob function in their operations. Given the attack's simplicity and the availability impact, organizations must treat this vulnerability as a top priority.
The urgency assessment based on the CVSS score indicates that organizations should prioritize patching immediately. Failure to address this vulnerability may lead to operational downtime and loss of customer trust.
