description

DHIS2 core versions 2.42.0 through before 2.42.5.1 and 2.43.0 through before 2.43.0.1 are affected. An attacker may achieve remote code execution through unsafe Java deserialization; the available evidence does not establish an authentication precondition.

mitigation

Upgrade dhis2-core to 2.42.5.1 or 2.43.0.1, or to DHIS2 2.44 or later.

fixed in 2.42.5.1, 2.43.0.1, 2.44 development branch after PR #24162
