Business recommendation:
------------------------
SEC Consult recommends to update publiXone to the latest version
(2020.015).
Vulnerability overview/description:
-----------------------------------
1) Account Takeover (CVE-2020-27179)
The password reset functionality can be abused to reset the
password of any
user. The token for the password-reset is encrypted and contains
the user ID
and a timestamp. The password for the encryption is hardcoded in
the
source-code of the Java applet. By using this key, an attacker can
create
valid tokens for any user and set the set password to a chosen
value.
2) Missing Access Control for API Endpoints (CVE-2020-27183)
In the source-code of the Java applet, several endpoints were
identified.
The endpoints are public and don't require authentication. The
components
communicate via serialized Java Objects.
Among others, the following actions are available:
- UploadFile
- DownloadFile
- GetUserData
- SendMail
- SetUserData
- CreateDir
3) Unauthenticated File Download (CVE-2020-27180)
Via the IXCopy endpoint, files can be downloaded by specifying a
unique
file ID. The ID is iterative and can be enumerated. No
authentication is
required to download the files, which are mostly Adobe XCopy files.
This
issue is not related to the 'DownloadFile' vulnerability described
in 2).
4) Hardcoded AES Keys (CVE-2020-27181)
The web application uses a Java applet for editing marketing
materials. In the
decompiled source-code of the applet a hardcoded AES key has been
identified.
This can be exploited to accomplish the account takeover, described
in 1).
5) Reflected Cross-Site Scripting (XSS) (CVE-2020-27182)
Several reflected cross-site scripting vulnerabilities have been
identified.
