Bug ID: 3488
Summary: scp fails to locate remote paths containing a
non-empty square bracket pair
Product: Portable OpenSSH
Version: 9.1p1
Hardware: amd64
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: scp
Assignee: [email protected]
Reporter: [email protected]
I'm noticing this issue in OpenSSH 9.0p1 and 9.1p1.
If the remote path contains a matched square bracket pair (i.e. '['
followed sometime later by ']'), and there is any text between the
opening and closing square brackets, scp fails to locate that path.
If I have the following files on a remote server:
A) foo[]
B) foo]0[
C) foo[0
D) foo0]
E) foo[0]
F) foo[x]
G) bar[/foo]
H) bar[/]foo
And on a client I try to scp them like so:
A) scp -pr "user@host:/path/foo[]" .
B) scp -pr "user@host:/path/foo]0[" .
C) scp -pr "user@host:/path/foo[0" .
D) scp -pr "user@host:/path/foo0]" .
E) scp -pr "user@host:/path/foo[0]" .
F) scp -pr "user@host:/path/foo[x]" .
G) scp -pr "user@host:/path/bar[/foo]" .
H) scp -pr "user@host:/path/bar[/]foo" .
A, B, C, and D will succeed. E, F, G, and H will all fail with the
error:
scp: /path/...: No such file or directory
And the path in the error message will match exactly the path that does
in fact exist.
As you can see with case H, the pair doesn't have to occur within a
single path component, it can occur anywhere across the entire path.
