## From the sources

IBM Aspera Faspex 4.4.2 Patch Level 1 and earlier could allow a remote attacker to execute arbitrary code on the system, caused by a YAML deserialization flaw. By sending a specially crafted obsolete API call, an attacker could exploit this vulnerability to execute arbitrary code on the system. The obsolete API call was removed in Faspex 4.4.2 PL2. IBM X-Force ID: 243512.
