OX App Suite: Improper Neutralization of Special Elements used in an SQL Command
CVE-2023-29047 is a high-severity improper neutralization of special elements used in an SQL command vulnerability in OX App Suite from OX Software, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, without any action from a user. Affected OX App Suite versions: 7.10.6-rev5 and earlier; 8.12 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.34% 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 Open-xchange Appsuite to 7.10.6 or a later version.
- Read the advisory on documentation.open-xchange.com for workarounds and exact fixed builds.

Official description
Imageconverter API endpoints provided methods that were not sufficiently validating and sanitizing client input, allowing to inject arbitrary SQL statements. An attacker with access to the adjacent network and potentially API credentials, could read and modify database content which is accessible to the imageconverter SQL user account. None No publicly available exploits are known.

The underlying weakness: Improper Neutralization of Special Elements used in an SQL Command
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using persistence layers such as Hibernate or Enterprise Java Beans, which can provide significant protection against SQL injection if used properly.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
