Cloud Mobility for Dell Storage: Improper Certificate Validation
CVE-2023-23690 is a high-severity improper certificate validation vulnerability in Cloud Mobility for Dell Storage from Dell, with a CVSS 3.1 base score of 7.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.3.3.X as the first without the flaw, so updating Cloud Mobility for Dell Storage to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.26% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Cloud Mobility for Dell Storage to 1.3.3.X or a later version.
- Update Cloud Mobility For Dell Emc Storage to 1.3.4.0 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Cloud Mobility for Dell EMC Storage, versions 1.3.0.X and below contains an Improper Check for Certificate Revocation vulnerability. A threat actor does not need any specific privileges to potentially exploit this vulnerability. An attacker could perform a man-in-the-middle attack and eavesdrop on encrypted communications from Cloud Mobility to Cloud Storage devices. Exploitation could lead to the compromise of secret and sensitive information, cloud storage connection downtime, and the integrity of the connection to the Cloud devices.

The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
