Ninja: Inadequate Encryption Strength
CVE-2024-36823 is a high-severity inadequate encryption strength vulnerability in Ninja from Ninjaframework, 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. Affected Ninja versions: 7.0.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.78% chance of exploitation within 30 days, higher than 57% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Ninja 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 |
|---|---|---|---|
| Ninjaframework | Ninja | 7.0.0 | Not stated |

Official description
The encrypt() function of Ninja Core v7.0.0 was discovered to use a weak cryptographic algorithm, leading to a possible leakage of sensitive information.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Inadequate Encryption Strength
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
How developers prevent this class of flaw
- Use an encryption scheme that is currently considered to be strong by experts in the field.
