CVE-2024-24786 is classified as a high-severity vulnerability with a CVSS score of 7.5. This vulnerability allows the protojson.Unmarshal function to enter an infinite loop when attempting to unmarshal certain forms of invalid JSON. This condition can occur when unmarshaling into a message that contains a google.protobuf.Any value or when the UnmarshalOptions.DiscardUnknown option is set.
The infinite loop could lead to denial of service, impacting the availability of the affected systems. Given the high severity and potential for significant disruption, organizations should prioritize patching immediately.
Currently, there are no known exploits associated with this vulnerability, but the exploitability score is classified as high. Organizations should remain vigilant to ensure they address this vulnerability in their patch management cycles.
The urgency for remediation is underscored by the potential for system downtime, which can have cascading effects on business operations. Security teams should assess their environment for exposure to this vulnerability.
Vulnerability Details
The vulnerability is specifically related to the protojson.Unmarshal function used in certain programming environments. The CVSS score indicates a high severity level, as the potential impact on availability is significant.
As of the publication date on March 5, 2024, the vulnerability has not been linked to a specific vendor or product, indicating a potential risk across various implementations that utilize this function.
Technical Analysis
This vulnerability stems from a flaw in the handling of invalid JSON data. When certain invalid formats are passed to the protojson.Unmarshal function, the function can enter an infinite loop, leading to a denial of service situation.
The attack vector is classified as network-based, meaning that an attacker could potentially trigger this vulnerability remotely. The attack complexity is low, requiring no special privileges or user interaction.
If exploited, the availability impact is high, as the application may become unresponsive. Organizations are advised to implement monitoring to detect unusual behavior that may indicate attempts to exploit this vulnerability.
Risk & Impact Analysis
Risk to organizations includes potential downtime and service disruption. As applications become increasingly integrated and reliant on JSON data formats, the exploitation of this vulnerability could lead to widespread availability issues.
Given the high CVSS score and the nature of the vulnerability, organizations should assess the risk associated with their specific use of the protojson.Unmarshal function and prioritize patching as part of their security strategy.
