Multiple buffer overflows in CA BrightStor ARCserve Backup r11.5 SP1 and earlier, r11.1, and 9.01; BrightStor ARCserve Backup for Windows r1

Noroxi assessment

Priority: Plan (action score 54/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 79.5% (FIRST EPSS); higher than 99.6% of all records.
  • No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
