CVE-2023-20508: Improper access control in the ASP could allow a privileged attacker to perform an out-of-bounds write to a memory location not controlled b

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.13% (FIRST EPSS).
  • Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. Special conditions such as timing or configuration are required.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Improper access control in the ASP could allow a privileged attacker to perform an out-of-bounds write to a memory location not controlled by the attacker, potentially leading to loss of confidentiality, integrity, or availability.
