There is a possible file disclosure of locally encrypted files in Active Support. This vulnerability has been assigned the CVE identifier CVE-2023-38037. Versions Affected: >= 5.2.0 Not affected: < 5.2.0 Fixed Versions: 7.0.7.1, 6.1.7.5
There is a vulnerability in ActiveSupport if the new bytesplice method is called on a SafeBuffer with untrusted user input. This vulnerability has been assigned the CVE identifier CVE-2023-28120. Versions Affected: All. Not affected: None Fixed Versions: 7.0.4.3, 6.1.7.3 Impact ActiveSupport uses the SafeBuffer string subclass to tag strings as html_safe after they have been sanitized. When these strings are mutated, the tag is should be removed to mark them …
A regular expression based DoS vulnerability in Active Support <6.1.7.1 and <7.0.4.1. A specially crafted string passed to the underscore method can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability.
There is a possible regular expression based DoS vulnerability in Active Support. A specially crafted string passed to the underscore method can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability. This affects String#underscore, ActiveSupport::Inflector.underscore, String#titleize, and any other methods using these. All users running an affected release …
A deserialization of untrusted data vulnernerability exists in rails, rails that can allow an attacker to unmarshal user-provided objects in MemCacheStore and RedisCacheStore potentially resulting in an RCE.
active-support could allow a remote attacker to execute arbitrary code on the system, caused by containing a malicious backdoor. An attacker could exploit this vulnerability to execute arbitrary code on the system.
Cross-site scripting (XSS) vulnerability in Ruby on Rails 2.x before 2.2.3, and 2.3.x before 2.3.4, allows remote attackers to inject arbitrary web script or HTML by placing malformed Unicode strings into a form helper.
The cross-site scripting (XSS) prevention feature in Ruby on Rails 2.x before 2.3.12, 3.0.x before 3.0.8, and 3.1.x before 3.1.0.rc2 does not properly handle mutation of safe buffers, which makes it easier for remote attackers to conduct XSS attacks via crafted strings to an application that uses a problematic string method, as demonstrated by the sub method.
Cross-site scripting (XSS) vulnerability in activesupport/lib/active_support/core_ext/string/output_safety.rb in Ruby on Rails 2.x before 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5 allows remote attackers to inject arbitrary web script or HTML via a malformed Unicode string, related to a "UTF-8 escaping vulnerability."
A certain algorithm in Ruby on Rails 2.1.0 through 2.2.2, and 2.3.x before 2.3.4, leaks information about the complexity of message-digest signature verification in the cookie store, which might allow remote attackers to forge a digest via multiple attempts.
Cross-site scripting (XSS) vulnerability in activesupport/lib/active_support/core_ext/string/output_safety.rb in Ruby on Rails before 2.3.16, 3.0.x before , 3.1.x before 3.1.8, and 3.2.x before 3.2.8 might allow remote attackers to inject arbitrary web script or HTML via vectors involving a ' (quote) character.
When a Hash containing user-controlled data is encoded as JSON (either through Hash#to_json or ActiveSupport::JSON.encode), Rails does not perform adequate escaping that matches the guarantee implied by the escape_html_entities_in_json option (which is enabled by default). If this resulting JSON string is subsequently inserted directly into an HTML page, the page will be vulnerable to XSS attacks.
Specially crafted XML documents can cause applications to raise a SystemStackError and potentially cause a denial of service attack. This nonly impacts applications using REXML or JDOM as their XML processor. Other XML processors that Rails supports are not impacted.
There is a vulnerability in the JDOM backend to ActiveSupport's XML parser. you should upgrade or use one of the work arounds immediately.
There is a vulnerability in the JSON code for Ruby on Rails which allows attackers to bypass authentication systems, inject arbitrary SQL, inject and execute arbitrary code, or perform a DoS attack on a Rails application.
Ruby on Rails contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate direct manipulations of SafeBuffer objects via '[]' and other methods. This may allow a user to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
