Remote Code Execution (RCE)

activerecord is vulnerable to Remote Code Execution RCE. Active Record uses YAML.unsafeload to convert the YAML data in to Ruby objects allowing an attacker who can manipulate data in the database to execute malicious code remotely...

Active Record RCE bug with Serialized Columns

When serialized columns that use YAML the default are deserialized, Rails uses YAML.unsafeload to convert the YAML data in to Ruby objects. If an attacker can manipulate data in the database via means like SQL injection, then it may be possible for the attacker to escalate to an RCE. There are no...

GitLab: RCE via unsafe inline Kramdown options when rendering certain Wiki pages

Summary When rendering wiki content with certain extensions such as .rmd, renderwikicontent will call othermarkupunsafe which will end up calling GitHub::Markup.render from the github-markup gem. Files with any extension can be uploaded by checking out the wiki with git, commiting the files and...

ActiveSupport potentially unintended unmarshalling of user-provided objects in MemCacheStore and RedisCacheStore

In ActiveSupport, there is potentially unexpected behaviour in the MemCacheStore and RedisCacheStore where, when untrusted user input is written to the cache store using the raw: true parameter, re-reading the result from the cache can evaluate the user input as a Marshalled object instead of pla...
