CVE-2024-22425 is a critical-severity improper restriction of excessive authentication attempts vulnerability in RecoverPoint for VMs from Dell, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected RecoverPoint for VMs versions: 5.3 SP2; 5.3 SP2 P1; 5.3 SP2 P2, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of RecoverPoint for VMs you run against the affected versions below, and install the vendor's latest release.
- 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
Dell RecoverPoint for Virtual Machines 5.3.x, 6.0.SP1 contains a brute force/dictionary attack vulnerability. An unauthenticated remote attacker could potentially exploit this vulnerability, leading to launch a brute force attack or a dictionary attack against the RecoverPoint login form. This allows attackers to brute-force the password of valid users in an automated manner.

The underlying weakness: Improper Restriction of Excessive Authentication Attempts
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.
How developers prevent this class of flaw
- Common protection mechanisms include: Disconnecting the user after a small number of failed attempts Implementing a timeout Locking out a targeted account Requiring a computational task on the user's part.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator.
