### Summary When using the `Rack::Session::Pool` middleware, simultaneous rack requests can restore a deleted rack session, which allows the unauthenticated user to occupy that session. ### Details [Rack session middleware](https://github.com/rack/rack/blob/v2.2.13/lib/rack/session/abstract/id.rb#L263-L270) prepares the session at the beginning of request, then saves is back to the store with possible changes applied by host rack application. This way the session becomes to be a subject of race conditions in general sense over concurrent rack requests. ### Impact When using the `Rack::Session::Pool` middleware, and provided the attacker can acquire a session cookie (already a major issue), the session may be restored if the attacker can trigger a long running request (within that same session) adjacent to the user logging out, in order to retain illicit access even after a user has attempted to logout. ## Mitigation - Update to the latest version of `rack`, or - Ensure your appl...
An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().
Craft CMS stores arbitrary content provided by unauthenticated users in session files. This content could be accessed and executed, possibly using an independent vulnerability. Craft CMS redirects requests that require authentication to the login page and generates a session file on the server at `/var/lib/php/sessions`. Such session files are named `sess_[session_value]`, where `[session_value]` is provided to the client in a `Set-Cookie` response header. Craft CMS stores the return URL requested by the client without sanitizing parameters. Consequently, an unauthenticated client can introduce arbitrary values, such as PHP code, to a known local file location on the server. Craft CMS versions 5.7.5 and 4.15.3 have been released to address this issue.
Cross Site Scripting vulnerability in Koillection v.1.6.10 allows a remote attacker to escalate privileges via the collection, Wishlist and album components
### Summary When verifying SSL certificates, jruby-openssl is not verifying that the hostname presented in the certificate matches the one we are trying to connect to, meaning a MITM could just present _any_ valid cert for a completely different domain they own, and JRuby wouldn't complain. ### Details n/a ### PoC An example domain bad.substitutealert.com was created to present the a certificate for the domain s8a.me. The following script run in IRB in CRuby 3.4.3 will fail with `certificate verify failed (hostname mismatch)`, but will work just fine in JRuby 10.0.0.0 and JRuby 9.4.2.0, both of which use jruby-openssl version 0.15.3 ```ruby require "net/http" require "openssl" uri = URI("https://bad.substitutealert.com/") https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = true https.verify_mode = OpenSSL::SSL::VERIFY_PEER body = https.start { https.get(uri.request_uri).body } puts body ``` ### Impact Anybody using JRuby to make requests of external APIs, or scrapi...
A business logic vulnerability in Easy Appointments v1.5.1 allows attackers to cause a Denial of Service (DoS) via unspecified vectors.
### Impact It is possible to obtain user session cookies by submitting an HTML form as part of an Event Definition Remediation Step field. For this attack to succeed, the attacker needs a user account with permissions to create event definitions, while the user must have permissions to view alerts. Additionally, an active Input must be present on the Graylog server that is capable of receiving form data (e.g. a HTTP input, TCP raw or syslog etc). ### Patches ### Workarounds None, as long as the relatively rare prerequisites are met.

### Impact Two minor vulnerabilities were identified in the Graylog2 enterprise server, which can be combined to carry out a stored cross-site scripting attack. An attacker with the permission `FILES_CREATE` can exploit these vulnerabilities to upload arbitrary Javascript code to the Graylog2 server, which - upon requesting of the file by a user of the API browser - results in the execution of this Javascript code in the context of the Graylog frontend application. This enables the attacker to carry out authenticated API requests with the permissions of the logged-in user, thereby taking over the user session. ### Patches The generic API has been removed in 6.2.0 rendering the attack vector unreachable and additional escaping has been added.

`Match::get()` and `Match::ptr()` lack sufficient bounds checks, leading to potential out of bounds reads.
### Impact #### Mithril certification of Cardano database The Mithril network provides certification for snapshots of the Cardano database, enabling users to quickly bootstrap a Cardano node without relying on the slower peer-to-peer synchronization process. To generate a multi-signature, a minimum threshold of Cardano stake registered in the protocol must agree on signing the same message. In this context, a digest is computed from the internal files of the Cardano node's database. However, this mechanism has certain limitations. Specifically, some files are not identically generated across all Cardano nodes, and there is no API to provide consistent snapshots at a specific beacon on the Cardano chain: - All immutable files, except the last one (which is still being created), are used to compute the message - The last immutable file is excluded from the signature - The ledger state files are also excluded from the signature. #### Cardano node startup sequence A Cardano node can ...
