Noroxi assessment

Priority: Now (action score 99/100)

CISA has confirmed exploitation in the wild (Feb 21, 2023); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Mar 14, 2023.
A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Probability of exploitation in the next 30 days: 99.9% (FIRST EPSS); higher than 99.9% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
According to the record, no fixed version is available yet.

Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

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.

Root cause

Data received over the network is deserialized into the language’s native object format without verifying its source. Code paths inside the object can be triggered during deserialization.
