MMP: Improper Neutralization of Special Elements used in an SQL Command
CVE-2022-21176 is a high-severity improper neutralization of special elements used in an SQL command vulnerability in MMP from Airspan Networks, with a CVSS 3.1 base score of 7.5 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 v1.0.3 as the first without the flaw, so updating MMP to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.05% chance of exploitation within 30 days, higher than 65% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update MMP to v1.0.3 or a later version.
- Update PTP C-series to v2.8.6.1 or a later version.
- Update PTMP C-series and A5x to v2.5.4.1 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
MMP: All versions prior to v1.0.3, PTP C-series: Device versions prior to v2.8.6.1, and PTMP C-series and A5x: Device versions prior to v2.5.4.1 does not properly sanitize user input, which may allow an attacker to perform a SQL injection and obtain sensitive information.

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.
