SB2024072946 - Multiple vulnerabilities in esp-idf

Description

This security bulletin contains information about 3 vulnerabilities.

1) Infinite loop (CVE-ID: CVE-2024-24746)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in GATT server. A remote attacker can consume all available system resources and cause denial of service conditions.

2) Input validation error (CVE-ID: CVE-2020-26142)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. A remote attacker on the local network can inject arbitrary network packets, independent of the network configuration.

3) Improper authentication (CVE-ID: CVE-2023-52160)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P/U:Green

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in the PEAP implementation. A remote attacker can bypass authentication process by sending an EAP-TLV Success packet instead of starting Phase 2.

Successful exploitation of the vulnerability requires that wpa_supplicant is configured to not verify the network's TLS certificate during Phase 1 authentication.

Remediation
