GitHub Vulnerability Alerts
CVE-2022-30187
Summary
The Azure Storage Encryption library in Java and other languages is vulnerable to a CBC Padding Oracle attack, similar to CVE-2020-8911. The library is not vulnerable to the equivalent of CVE-2020-8912, but only because it currently only supports AES-CBC as encryption mode.
Severity
Moderate - The vulnerability poses insider risks/privilege escalation risks, circumventing controls for stored data.
Further Analysis
The Java Azure Blob Storage Encryption SDK is impacted by an issue that can result in loss of confidentiality and message forgery. The attack requires write access to the container in question, and that the attacker has access to an endpoint that reveals decryption failures (without revealing the plaintext) and that when encrypting the CBC option was chosen as content cipher.
This advisory describes the plaintext revealing vulnerabilities in the Java Azure Blob Storage Encryption SDK, with a similar issue in the other blob storage SDKs being present as well.
In the current version of the Azure Blob Storage crypto SDK, the only algorithm option that allows users to encrypt files is to AES-CBC, without computing a MAC on the data.
This exposes a padding oracle vulnerability: If the attacker has write access to the blob container bucket and can observe whether or not an endpoint with access to the key can decrypt a file (without observing the file contents that the endpoint learns in the process), they can reconstruct the plaintext with (on average) 128*length(plaintext) queries to the endpoint, by exploiting CBC's ability to manipulate the bytes of the next block and PKCS5 padding errors.

12.11.0 (2022-03-29)
Warning This release involves a bug fix that may change the behavior for some users. In previous versions,
the
tagparameter onBlobSasPermissionsdefaulted toTruemeaning a Blob SAS URL would include thetpermissionby default. This was not the intended behavior. This release adjusts
BlobSasPermissionso thetagpermission willdefault to
False, like all other permissions.Bugs Fixed
BlobSasPermissionswhere thetagpermission had a default value ofTrueandtherefore was being added to the SAS token by default.
