Description

sudo-rs Allows Low Privilege Users to Discover the Existence of Files in Inaccessible Folders

Summary

Users with no (or very limited) sudo privileges can determine whether files exists in folders that they otherwise cannot access using sudo --list <pathname>.

PoC

As root:

```

# mkdir /tmp/foo

# chmod a-rwx /tmp/foo

# touch /tmp/foo/secret_file

```

As a user without any (or limited) sudo rights:

```

$ sudo --list /tmp/foo/nonexistent_file

sudo-rs: '/tmp/foo/nonexistent_file': command not found

$ $ sudo --list /tmp/foo/secret_file

sudo-rs: Sorry, user eve may not run sudo on host.

```

I.e. the user can distinguish whether files exist.

Related

Original sudo (vulnerable version tested by us: 1.9.15p5) exhibited similar behaviour for files with the executable bit set.

Impact

Users with local access to a machine can discover the existence/non-existence of certain files, revealing potentially sensitive information in the file names. This information can also be used in conjunction with other attacks.

This issue was identified by sudo-rs developer Marc Schoolderman

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability none.

CVSS metrics in full

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

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: None.
  • Availability impact: None.
