CVE-2022-29229
CaSS Library, (npm:cassproject) has a missing cryptographic step when storing cryptographic keys that can allow a server administrator access to an account’s cryptographic keys.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
CaSS is a Competency and Skills System. CaSS Library, (npm:cassproject) has a missing cryptographic step when storing cryptographic keys that can allow a server administrator access to an account’s cryptographic keys. This affects CaSS servers using standalone username/password authentication, which uses a method that expects e2e cryptographic security of authorization credentials. The issue has been patched in 1.5.8, however, the vulnerable accounts are only resecured when the user next logs in using standalone authentication, as the data required to resecure the account is not available to the server. The issue may be mitigated by using SSO or client side certificates to log in. Please note that SSO and client side certificate authentication does not have this expectation of no-knowledge credential access, and cryptographic keys are available to the server administrator.
