Elasticsearch Memory Disclosure



This module exploits a memory disclosure vulnerability in Elasticsearch 7.10.0 to 7.13.3 (inclusive). A user with the ability to submit arbitrary queries to Elasticsearch can generate an error message containing previously used portions of a data buffer. This buffer could contain sensitive information such as Elasticsearch documents or authentication details. This vulnerability's output is similar to heartbleed.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/scanner/http/elasticsearch_memory_disclosure
msf auxiliary(elasticsearch_memory_disclosure) > show actions
msf auxiliary(elasticsearch_memory_disclosure) > set ACTION < action-name >
msf auxiliary(elasticsearch_memory_disclosure) > show options
    ...show and set options...
msf auxiliary(elasticsearch_memory_disclosure) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
