CVE-2021-43802

CWE-20
 

 
Etherpad is a real-time collaborative editor. In versions prior to 1.8.16, an attacker can craft an `*.etherpad` file that, when imported, might allow the attacker to gain admin privileges for the Etherpad instance. This, in turn, can be used to install a malicious Etherpad plugin that can execute arbitrary code (including system commands). To gain privileges, the attacker must be able to trigger deletion of `express-session` state or wait for old `express-session` state to be cleaned up. Core Etherpad does not delete any `express-session` state, so the only known attacks require either a plugin that can delete session state or a custom cleanup process (such as a cron job that deletes old `sessionstorage:*` records). The problem has been fixed in version 1.8.16. If users cannot upgrade to 1.8.16 or install patches manually, several workarounds are available. Users may configure their reverse proxies to reject requests to `/p/*/import`, which will block all imports, not just `*.etherpad` imports; limit all users to read-only access; and/or prevent the reuse of `express_sid` cookie values that refer to deleted express-session state. More detailed information and general mitigation strategies may be found in the GitHub Security Advisory.

CVE-2020-22781

CWE-89
 

 
In Etherpad < 1.8.3, a specially crafted URI would raise an unhandled exception in the cache mechanism and cause a denial of service (crash the instance).

 
 
CVE-2020-22782

NVD-CWE-noinfo
 

 
Etherpad < 1.8.3 is affected by a denial of service in the import functionality. Upload of binary file to the import endpoint would crash the instance.

 
 
CVE-2020-22785

CWE-770
 

 
Etherpad < 1.8.3 is affected by a missing lock check which could cause a denial of service. Aggressively targeting random pad import endpoints with empty data would flatten all pads due to lack of rate limiting and missing ownership check.

 
 
CVE-2020-22783

CWE-312
 

 
Etherpad <1.8.3 stored passwords used by users insecurely in the database and in log files. This affects every database backend supported by Etherpad.

CVE-2015-3309

CWE-22
 

 
Directory traversal vulnerability in node/utils/Minify.js in Etherpad 1.1.2 through 1.5.4 allows remote attackers to read arbitrary files with permissions of the user running the service via a .. (dot dot) in the path parameter of HTTP API requests. NOTE: This vulnerability is due to an incomplete fix to CVE-2015-3297.

CVE-2015-2298

CWE-200
 

 
node/utils/ExportEtherpad.js in Etherpad 1.5.x before 1.5.2 might allow remote attackers to obtain sensitive information by leveraging an improper substring check when exporting a padID.
