Tested the viewing of http://server/log/messages on Axis 2100 model, and =
it is
vulnerable.

Didn't try to check the overwrite vulnerability - I'd rather not, just =
in case.

1) INFORMATION DISCLOSURE

http-requests to:

---*---
http://server/support/messages
---*---

responds with /var/log/messages.
it is not password protected and might disclose sensitive information.


2) DOS / OVERWRITING SYSTEM-FILES
requesting:
---*---
http://server/axis-cgi/buffer/command.cgi?
buffername=3DX&
prealarm=3D1&
postalarm=3D1&
do=3Dstart&
uri=3D/jpg/quad.jpg&
format=3D[bad input]
---*---

allows an attacker to overwrite important files on the system (all fifos =
for
example) leading to an effective DOS-attack.


3) ARBITRARY FILE CREATION

a request like:
---*---
/axis-cgi/buffer/command.cgi?whatever params buffername=3D[relative path =
to
directory] format=3D[relative path to arbitrary file name]
---*---

will create [relative path to arbitrary file name] or [relative path to =
a.
directory]

if somebody is able to change content of error messages he might be able =
to
create and execute arbitrary script-files(php fE.).

Sorry, can't reproduce it on a 2100 with firmware 2.33.1. It prompts me
for authentication, and *only* the root username/password pair grant me
access to /support/messages (not /log/messages as you wrote). Other
less privileged username/password pairs (yes, I've enabled those) return
a "password is incorrect" error.

If you don't password-protect the root account you get of course what
you deserve. And if you claim a product is vulnerable without specifying
which software (here firmware) revision(s) you've tested, you don't
sound terribly convincing.

[Side note:
For some strange reason the 2.33.1 "service release" of the firmware is
not advertised on the www.axis.com firmware download pages; you may
however find it by anonymous ftp in the sr/ subdirectory. See the
message from product-security@axis.com to BugTraq on 2002-12-20.]

Product tested : AXIS 2401 release 2.32

That's fine

> 3) ARBITRARY FILE CREATION

Don't work. Ask for a login/pass.
