CVE-2024-38883: An issue in Horizon Business Services Inc. Caterease Software allows a remote
attacker to perform a Drop Encryption Level attack due to the selection of a less-secure algorithm during
negotiation.
Vulnerability Type: CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm
Downgrade')
Vendor of the Product: Horizon Business Services Inc.
Affected Product: Caterease Software
Affected Versions: 16.0.1.1663 through 24.0.1.2405
Attack Vector: Remote
Attack Type: CAPEC-620: Drop Encryption Level
Vulnerability Summary: Caterease Software does not enforce encryption during the TDS7 PreLogin
authentication sequence, making it susceptible to a downgrade attack. Attackers can intercept the initial
handshake between the Caterease Software client and the SQL server and manipulate the server's
response to indicate that encryption is not supported. As a result, the client will proceed to send sensitive
information, including database credentials, in plaintext over the network.
By exploiting this vulnerability, attackers can capture the unencrypted credentials and use them to gain
unauthorized access to the SQL database. This exposure not only compromises the confidentiality of the
credentials but also allows attackers to read, modify, or delete database records, leading to significant data
breaches and integrity issues.
CVSS Base Score: Critical Risk - 9.3
