CVE-2021-37202
Estado: ModificadaAlta (7.8)—
A vulnerability has been identified in NX 1980 Series (All versions < V1984), Solid Edge SE2021 (All versions < SE2021MP8). The IFC adapter in affected application contains a use-after-free vulnerability that could be triggered while parsing user-supplied IFC files. An attacker could leverage this vulnerability to execute code in the context of the current process.
