CVE-2024-21909: CWE-407 Inefficient Algorithmic Complexity
PeterO.Cbor versions 4.0.0 through 4.5.0 are vulnerable to a denial of service vulnerability. An attacker may trigger the denial of service condition by providing crafted data to the DecodeFromBytes or other decoding mechanisms in PeterO.Cbor. Depending on the usage of the library, an unauthenticated and remote attacker may be able to cause the denial of service condition.
AI Analysis
Technical Summary
CVE-2024-21909 affects PeterO.Cbor versions 4.0.0 through 4.5.0 and is classified as CWE-407 (Inefficient Algorithmic Complexity). The vulnerability arises when specially crafted input data is processed by decoding methods like DecodeFromBytes, leading to excessive resource consumption and denial of service. The attack vector is network-based with no privileges or user interaction required. There is no information about an available patch or vendor advisory in the provided data.
Potential Impact
An unauthenticated remote attacker can cause a denial of service by exploiting inefficient algorithmic complexity in the decoding functions of PeterO.Cbor. This results in service disruption or application unavailability. There is no indication of confidentiality or integrity impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider implementing input validation or limiting resource usage during decoding operations to mitigate potential denial of service.
