caterease: Selection of Less-Secure Algorithm During Negotiation
CVE-2024-38883 is a critical-severity selection of less-secure algorithm during negotiation vulnerability in caterease from Horizoncloud, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected caterease versions: 16.0.1.1663 through 24.0.1.2405. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.35% 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 caterease you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Horizoncloud | caterease | 16.0.1.1663 through 24.0.1.2405 | Not stated |

Official description
An issue in Horizon Business Services Inc. Caterease 16.0.1.1663 through 24.0.1.2405 and possibly later versions, allows a remote attacker to perform a Drop Encryption Level attack due to the selection of a less-secure algorithm during negotiation.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Selection of Less-Secure Algorithm During Negotiation
A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used in a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties.
