CVE-2009-2564: Adobe Acrobat Reader

High severity, CVSS 7.2. EPSS: 5.6% chance of exploitation in the next 30 days.

NOS Microsystems getPlus Download Manager, as used in Adobe Reader 1.6.2.36 and possibly other versions, Corel getPlus Download Manager before 1.5.0.48, and possibly other products, installs NOS\bin\getPlus_HelperSvc.exe with insecure permissions (Everyone:Full Control), which allows local users to gain SYSTEM privileges by replacing getPlus_HelperSvc.exe with a Trojan horse program, as demonstrated by use of getPlus Download Manager within Adobe Reader. NOTE: within Adobe Reader, the scope of this issue is limited because the program is deleted and the associated service is not automatically launched after a successful installation and reboot.

Affected products

  • Adobe Acrobat Reader: version 9.0 only; version 9.1 only
  • Corel Getplus Download Manager: version 1.5.0.48 only
  • Nos Microsystems Getplus Download Manager: version 1.6.2.36 only
