What is CVE-2023-20862?
CVE-2023-20862 is a medium-severity authentication bypass vulnerability in Netapp Active Iq Unified Manager, published on 19 Apr 2023. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
In Spring Security, versions 5.7.x prior to 5.7.8, versions 5.8.x prior to 5.8.3, and versions 6.0.x prior to 6.0.3, the logout support does not properly clean the security context if using serialized versions. Additionally, it is not possible to explicitly save an empty security context to the HttpSessionSecurityContextRepository. This vulnerability can keep users authenticated even after they performed logout. Users of affected versions should apply the following mitigation. 5.7.x users should upgrade to 5.7.8. 5.8.x users should upgrade to 5.8.3. 6.0.x users should upgrade to 6.0.3.
