CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability classified as critical was found in mbed TLS 3.6.0. The impacted element is the function mbedtls_ecdsa_der_to_raw/mbedtls_ecdsa_raw_to_der. Such manipulation of the argument bits leads to stack-based overflow. This vulnerability is listed as CVE-2024-45158. There is no available exploit. Upgrading the affected component is advised.

Detailsinfo

A vulnerability was found in mbed TLS 3.6.0. It has been rated as critical. Affected by this issue is the function mbedtls_ecdsa_der_to_raw/mbedtls_ecdsa_raw_to_der. The manipulation of the argument bits with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in Mbed TLS 3.6 before 3.6.1. A stack buffer overflow in mbedtls_ecdsa_der_to_raw() and mbedtls_ecdsa_raw_to_der() can occur when the bits parameter is larger than the largest supported curve. In some configurations with PSA disabled, all values of bits are affected. (This never happens in internal library calls, but can affect applications that call these functions directly.)

The advisory is shared for download at mbed-tls.readthedocs.io. This vulnerability is handled as CVE-2024-45158 since 08/22/2024. The exploitation is known to be easy. There are known technical details, but no exploit is available.

Upgrading to version 3.6.1 eliminates this vulnerability.
