CISA KEV Advisory
IBM Aspera Faspex Code Execution Vulnerability
IBM Aspera Faspex could allow a remote attacker to execute code on the system, caused by a YAML deserialization flaw.
Apply updates per vendor instructions.
Risk Analysis
IBM Aspera Faspex is vulnerable to a YAML deserialization flaw, which could allow a remote attacker to execute code on the system. The high EPSS score of 0.94345 indicates a very high likelihood of exploitation, making this a critical issue.
This vulnerability is actively exploited in the wild and is included in CISA's KEV catalog. The deserialization flaw makes it remotely exploitable for code execution.
Update IBM Aspera Faspex to a patched version to address the YAML deserialization vulnerability and prevent remote code execution.
Technical Analysis
CVE-2022-47986 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2022-47986 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
