GHSA-F632-9449-3J4W
Vulnerability from github – Published: 2024-11-18 15:33 – Updated: 2026-06-18 20:22Description:
The fix for improvement 69333 caused pooled JSP tags not to be released after use which in turn could cause output of some tags not to escaped as expected. This unescaped output could lead to XSS.
Versions Affected:
- Apache Tomcat 11.0.0
- Apache Tomcat 10.1.31
- Apache Tomcat 9.0.96
Mitigation:
Users of the affected versions should apply one of the following mitigations: - Upgrade to Apache Tomcat 11.0.1 or later - Upgrade to Apache Tomcat 10.1.33 or later Note: 10.1.32 was not released - Upgrade to Apache Tomcat 9.0.97 or later

GHSA-F686-HW9C-XW9C
Vulnerability from github – Published: 2024-10-30 14:37 – Updated: 2024-10-31 19:36Impacted Products
Snowflake JDBC driver versions >= 3.2.6 & <= 3.19.1 are affected.
Introduction
Snowflake recently identified an issue affecting JDBC drivers that can result in data being uploaded to an encrypted stage without the additional layer of protection provided by client side encryption. The issue, which affects only a subset of accounts hosted on Azure and GCP deployments (AWS deployments are not affected), manifests in instances where customers create a stage using a JDBC driver with the CLIENT_ENCRYPTION_KEY_SIZE account parameter set to 256-bit rather than the default 128-bit. The data is still protected by TLS in transit and server side encryption at rest. This missed layer of the additional protection is not visible to the affected customers.
Incorrect Security Setting Vulnerability
Description
Snowflake identified an incorrect security setting in Snowflake JDBC drivers. Snowflake has evaluated the severity of the issue and determined it was in medium range with a maximum CVSSv3 base score of 5.9.
Scenarios and attack vector(s)
Users of Snowflake JDBC drivers with accounts on Azure and GCP deployments who set the parameter CLIENT_ENCRYPTION_KEY_SIZE = 256 were subject to this incorrect security setting vulnerability as it could result in data being uploaded to a stage without an additional layer for encryption.
Our response
On July 23, 2024, Snowflake discovered this vulnerability. On 10/28/2024, Snowflake released a patch in Snowflake JDBC driver Version 3.20.0. The patch fixes the incorrect security setting.
Resolution
We strongly recommend users to upgrade to 3.20.0 or later versions as soon as possible.

This allows an attacker to retrieve the encrypted passwords from sshProfiles.jsd and encryptionProfiles.jsd and decrypt them to recover cleartext passwords. All 10.x up to and including 10.25 and all 11.x up to and including 11.14 are verified to be affected.

Mitigation
Use an encryption scheme that is currently considered to be strong by experts in the field.
CAPEC-112: Brute Force
In this attack, some asset (information, functionality, identity, etc.) is protected by a finite secret value. The attacker attempts to gain access to this asset by using trial-and-error to exhaustively explore all the possible secret values in the hope of finding the secret (or a value that is functionally equivalent) that will unlock the asset.
CAPEC-192: Protocol Analysis
An adversary engages in activities to decipher and/or decode protocol information for a network or application communication protocol used for transmitting information between interconnected nodes or systems on a packet-switched data network. While this type of analysis involves the analysis of a networking protocol inherently, it does not require the presence of an actual or physical network.
CAPEC-20: Encryption Brute Forcing
An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.
