Detail

  • CVE-2022-27624

    • Severity: Critical
    • CVSS3 Base Score: 10.0
    • CVSS3 Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
    • A vulnerability regarding improper restriction of operations within the bounds of a memory buffer is found in the packet decryption functionality of Out-of-Band (OOB) Management. This allows remote attackers to execute arbitrary commands via unspecified vectors. The following models with Synology DiskStation Manager (DSM) versions before 7.1.1-42962-2 may be affected: DS3622xs+, FS3410, and HD6500.
  • CVE-2022-27625

    • Severity: Critical
    • CVSS3 Base Score: 10.0
    • CVSS3 Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
    • A vulnerability regarding improper restriction of operations within the bounds of a memory buffer is found in the message processing functionality of Out-of-Band (OOB) Management. This allows remote attackers to execute arbitrary commands via unspecified vectors. The following models with Synology DiskStation Manager (DSM) versions before 7.1.1-42962-2 may be affected: DS3622xs+, FS3410, and HD6500.
  • CVE-2022-27626

    • Severity: Critical
    • CVSS3 Base Score: 10.0
    • CVSS3 Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
    • A vulnerability regarding concurrent execution using shared resource with improper synchronization ('Race Condition') is found in the session processing functionality of Out-of-Band (OOB) Management. This allows remote attackers to execute arbitrary commands via unspecified vectors. The following models with Synology DiskStation Manager (DSM) versions before 7.1.1-42962-2 may be affected: DS3622xs+, FS3410, and HD6500.
  • CVE-2022-3576

    • Severity: Moderate
    • CVSS3 Base Score: 5.3
    • CVSS3 Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
    • A vulnerability regarding out-of-bounds read is found in the session processing functionality of Out-of-Band (OOB) Management. This allows remote attackers to obtain sensitive information via unspecified vectors. The following models with Synology DiskStation Manager (DSM) versions before 7.1.1-42962-2 may be affected: DS3622xs+, FS3410, and HD6500.
