Tag: File Disclosure

An information exposure is the unintentional disclosure of information to an actor that is not explicitly authorized to have access to that information.

The information either
* is regarded as sensitive within the product’s own functionality, such as a private message; or
* provides information about the product or its environment that could be useful in an attack but is normally not available to the attacker, such as the installation path of a product that is remotely accessible.

Many information exposures are resultant (e.g. PHP script error revealing the full path of the program), but they can also be primary (e.g. timing discrepancies in cryptography). There are many different types of problems that involve information exposures. Their severity can range widely depending on the type of information that is revealed.

Vendor response
Horde Groupware was informed of the vulnerability, to which they response with:
“this has already been reported earlier by someone else, and is already fixed in the latest Gollem and Horde Groupware releases.

Besides that, it’s not sufficient to have a list of the server’s users, you also need to exactly know the file name and path that you want to download. Finally, this only works on certain backends, where Horde alone is responsible for authentication, i.e. it won’t work with backends that require explicit authentication.”

CVE: CVE-2017-15235
