Description

Nextcloud is an open source content collaboration platform. From versions 0.7.0 to before 0.7.7, 0.8.0 to before 0.8.10, 0.9.0 to before 0.9.8, and 1.0.0 to before 1.0.4, an authenticated attacker with access to the Tables app may be able to execute arbitrary up to 20 bytes long SQL queries, through a stored injection. With carefully crafted input it is possible to break out of the length limitation. The attacker could use this to extract information from the database, or modify data. This issue has been patched in versions 0.7.7, 0.8.10, 0.9.8, 1.0.4, and 2.0.0.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is high, an attacker needs low-level privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity high, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Changed — a successful attack reaches components beyond the vulnerable one.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: None.
