Vendor description:


Bitdefender GravityZone lets enterprises control and protect the heterogeneous

environments of today. The solution combines highly optimized virtualization

aware security with leading detection technologies and a fresh, but proven,

architecture. It empowers administrators with features adapted to reduce the

daily security hassle and eliminate the need for point solutions with unified

protection across virtualized, physical, and mobile endpoints. Unlike other

solutions that bolt-on modules to an aging architecture, the GravityZone

Control Center dashboard has been designed specifically to unify monitoring

and security management in a single simple and accessible interface.





Business recommendation:


Attackers are able to completely compromise the Bitdefender GravityZone

solution as they can gain system and database level access.

Furthermore attackers can manage all endpoints.


The Bitdefender GravityZone can be used as an entry point into the target

infrastructure (lateral movement, privilege escalation).


It is highly recommended by SEC Consult not to use this software until a

thorough security review has been performed by security professionals and all

identified issues have been resolved.



Vulnerability overview/description:


1) Unauthenticated local file disclosure (Web Console, Update Server)

Unauthenticated users can read arbitrary files from the filesystem with the

privileges of the "nginx" operating system user. These files include

configuration files containing sensitive information such as clear text

passwords which can be used in further attacks.


Separate vulnerabilities affecting both Web Console and Update Server were




2) Insecure service configuration / design issues

The MongoDB database which is offered via the network by default (TCP ports

27017, 28017) can be accessed using hardcoded credentials which can't be

changed. The overall system design requires the database to be accessible via

the network.

All relevant GravityZone configuration data can be accessed and changed. This

includes the user table.


Excerpt from the documentation describing the TCP port 27017:

"Default port used by the Communication Server and Control Center to access

the Database."



3) Missing authentication

Authentication is not required for certain scripts in the web UI. This

allows unauthenticated attackers to execute administrative functions without

prior authentication.



Proof of concept:


1) Unauthenticated local file disclosure (Web Console, Update Server)

Arbitrary files can be downloaded via a vulnerable script:

https:// <host>/webservice/CORE/downloadFullKitEpc/a/1?id=../../../../../etc/passwd


The Update Server is vulnerable to local file disclosure as well. Arbitrary

files can be downloaded using the following HTTP request:


GET /%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/etc/passwd HTTP/1.1

Host: <host>:7074


2) Insecure service configuration / Design issues

Attackers can connect to MongoDB on TCP ports 27017 and 28017 using the

following hardcoded credentials:

Username: <removed>

Password: <removed>


Detailed proof of concept exploits have been removed for this vulnerability.


3) Missing authentication

Authentication is not required for the following script:

/webservice/CORE/downloadSignedCsr (Unauthenticated certificate upload)




Vulnerable / tested versions:


The vulnerabilities have been verified to exist in GravityZone,

which was the most recent version at the time of discovery.
