U.S. Cybersecurity Agency CISA Adds Three New Vulnerabilities in KEV Catalog

The U.S. Cybersecurity and Infrastructure Security Agency (CISA)
on Tuesday added^[1]
three security flaws to its Known Exploited Vulnerabilities (KEV)
catalog, based on evidence of active exploitation.

The list of shortcomings is as follows –

• CVE-2022-47986^[2] (CVSS score: 9.8) – IBM
  Aspera Faspex Code Execution Vulnerability
• CVE-2022-41223^[3] (CVSS score: 6.8) –
  Mitel MiVoice Connect Code Injection Vulnerability
• CVE-2022-40765^[4] (CVSS score: 6.8) –
  Mitel MiVoice Connect Command Injection Vulnerability

CVE-2022-47986 is described as a YAML deserialization flaw in
the file transfer solution that could allow a remote attacker to
execute code on the system.

Details of the flaw and a proof-of-concept (PoC) were shared^[5]
by Assetnote on February 2, a day after which the Shadowserver
Foundation said^[6]
it “picked up exploitation attempts” in the wild.

The active exploitation of the Aspera Faspex flaw comes shortly
after a vulnerability in Fortra’s GoAnywhere MFT-managed file
transfer software (CVE-2023-0669^[7]) was abused by threat
actors with potential links to the Clop ransomware operation.

CISA also added two flaws impacting Mitel MiVoice Connect
(CVE-2022-41223 and CVE-2022-40765) that could permit an
authenticated attacker with internal network access to execute
arbitrary code.

Exact specifics surrounding the nature of the attacks are
unclear. The vulnerabilities were patched by Mitel in October
2022.

In light of in-the-wild exploitation, Federal Civilian Executive
Branch (FCEB) agencies are required to apply the necessary updates
by March 14, 2023, to secure networks against potential
threats.

CISA, in a related development, also released^[8]
an Industrial Control Systems (ICS) advisory that relates to
critical flaws (CVE-2022-26377 and CVE-2022-31813) in Mitsubishi
Electric’s MELSOFT iQ AppPortal.

“Successful exploitation of these vulnerabilities could allow a
malicious attacker to make unidentified impacts such as
authentication bypass, information disclosure, denial-of-service,
or bypass IP address authentication,” the agency said^[9].
