The CSV grade import method contained an XSS risk for users importing the spreadsheet, if it contained unsafe content.

A remote code execution risk was identified in the Lesson activity. By default this was only available to teachers and managers.

ID numbers displayed in the quiz grading report required additional sanitizing to prevent a stored XSS risk.

Students in "Only see own membership" groups could see other students in the group, which should be hidden.

### Summary An issue in AsyncSSH v2.14.0 and earlier allows attackers to control the remote end of an SSH client session via packet injection/removal and shell emulation. ### Details The rogue session attack targets any SSH client connecting to an AsyncSSH server, on which the attacker must have a shell account. The goal of the attack is to log the client into the attacker's account without the client being able to detect this. At that point, due to how SSH sessions interact with shell environments, the attacker has complete control over the remote end of the SSH session. The attacker receives all keyboard input by the user, completely controls the terminal output of the user's session, can send and receive data to/from forwarded network ports, and is able to create signatures with a forwarded SSH Agent, if any. The result is a complete break of the confidentiality and integrity of the secure channel, providing a strong vector for a targeted phishing campaign against the user. For e...

An issue discovered in esptool 4.6.2 allows attackers to view sensitive information via weak cryptographic algorithm.

### Summary An issue in AsyncSSH v2.14.0 and earlier allows attackers to control the extension info message (RFC 8308) via a man-in-the-middle attack. ### Details The rogue extension negotiation attack targets an AsyncSSH client connecting to any SSH server sending an extension info message. The attack exploits an implementation flaw in the AsyncSSH implementation to inject an extension info message chosen by the attacker and delete the original extension info message, effectively replacing it. A correct SSH implementation should not process an unauthenticated extension info message. However, the injected message is accepted due to flaws in AsyncSSH. AsyncSSH supports the server-sig-algs and global-requests-ok extensions. Hence, the attacker can downgrade the algorithm used for client authentication by meddling with the value of server-sig-algs (e.g. use of SHA-1 instead of SHA-2). ### PoC <details> <summary>AsyncSSH Client 2.14.0 (simple_client.py example) connecting to Asyn...

### Impact This advisory addresses an issue when a DynamoDB Set attribute is marked as SIGN_ONLY in the AWS Database Encryption SDK (DB-ESDK) for DynamoDB. This also includes when a Set is part of a List or a Map. DB-ESDK for DynamoDB supports `SIGN_ONLY` and `ENCRYPT_AND_SIGN` attribute actions. In version 3.1.0 and below, when a Set type is assigned a `SIGN_ONLY` attribute action, there is a chance that signature validation of the record containing a Set will fail on read, even if the Set attributes contain the same values. The probability of a failure depends on the order of the elements in the Set combined with how DynamoDB returns this data, which is undefined. This update addresses the issue by ensuring that any Set values are canonicalized in the same order while written to DynamoDB as when read back from DynamoDB. ### Patches Fixed in version 3.1.1 We recommend all users upgrade as soon as possible. ### Workarounds None ### References For more information on how to addres...

# Introduction This write-up describes a vulnerability found in [Label Studio](https://github.com/HumanSignal/label-studio), a popular open source data labeling tool. The vulnerability was found to affect versions before `1.8.2`, where a patch was introduced. # Overview In [Label Studio version 1.8.1](https://github.com/HumanSignal/label-studio/tree/1.8.1), a hard coded Django `SECRET_KEY` was set in the application settings. The Django `SECRET_KEY` is used for signing session tokens by the web application framework, and should never be shared with unauthorised parties. However, the Django framework inserts a `_auth_user_hash` claim in the session token that is a HMAC hash of the account's password hash. That claim would normally prevent forging a valid Django session token without knowing the password hash of the account. However, any authenticated user can exploit an Object Relational Mapper (ORM) Leak vulnerability in Label Studio to leak the password hash of any account on the ...
