Summary

git-annex is vulnerable to an Information Exposure when decrypting files. A malicious server for a special remote could trick git-annex into decrypting a file that was encrypted to the user's gpg key. This attack could be used to expose encrypted data that was never stored in git-annex

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

"The git-annex package was found to have multiple vulnerabilities when
operating on untrusted data that could lead to arbitrary command
execution and encrypted data exfiltration.

CVE-2017-12976

git-annex before 6.20170818 allows remote attackers to execute
arbitrary commands via an ssh URL with an initial dash character in
the hostname, as demonstrated by an ssh://-eProxyCommand= URL, a
related issue to CVE-2017-9800, CVE-2017-12836, CVE-2017-1000116, and
CVE-2017-1000117.

CVE-2018-10857

git-annex is vulnerable to a private data exposure and exfiltration
attack. It could expose the content of files located outside the
git-annex repository, or content from a private web server on
localhost or the LAN.

CVE-2018-10859

git-annex is vulnerable to an Information Exposure when decrypting
files. A malicious server for a special remote could trick git-annex
into decrypting a file that was encrypted to the user's gpg key. This
attack could be used to expose encrypted data that was never stored in
git-annex

For Debian 8 'Jessie', these problems have been fixed in version
5.20141125+oops-1+deb8u2.

We recommend that you upgrade your git-annex packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
