Modem VoWiFi IKE DH Downgrade Allows Remote Info Disclosure
CVE-2024-20069 Published on June 3, 2024
In modem, there is a possible selection of less-secure algorithm during the VoWiFi IKE due to a missing DH downgrade check. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01286330; Issue ID: MSV-1430.
Vulnerability Analysis
CVE-2024-20069 can be exploited with network access, requires user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.
Weakness Type
What is an Algorithm Downgrade Vulnerability?
A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used as a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties. When a security mechanism can be forced to downgrade to use a less secure algorithm, this can make it easier for attackers to compromise the software by exploiting weaker algorithm. The victim might not be aware that the less secure algorithm is being used. For example, if an attacker can force a communications channel to use cleartext instead of strongly-encrypted data, then the attacker could read the channel by sniffing, instead of going through extra effort of trying to decrypt the data using brute force techniques.
CVE-2024-20069 has been classified to as an Algorithm Downgrade vulnerability or weakness.
