CWE-1258

Exposure of Sensitive System Information Due to Uncleared Debug Information

BaseDraftSimple12 CVEs
The hardware does not fully clear security-sensitive values, such as keys and intermediate values in cryptographic operations, when debug mode is entered.

Extended description

Security sensitive values, keys, intermediate steps of cryptographic operations, etc. are stored in temporary registers in the hardware. If these values are not cleared when debug mode is entered they may be accessed by a debugger allowing sensitive information to be accessible by untrusted parties.

Common consequences2

  • ConfidentialityRead Memory
  • Access ControlBypass Protection Mechanism

Potential mitigations1

  1. Architecture and Design

    Whenever debug mode is enabled, all registers containing sensitive assets must be cleared.

CVE-2024-36913

In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: vmbus: Leak pages if set_memory_encrypted() fails In CoCo VMs it is possible for the untrusted host to cause set_memory_encrypted() or set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues. VMBus code could free decrypted pages if set_memory_encrypted()/decrypted() fails. Leak the pages if this happens.

CVE-2024-36912

In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: vmbus: Track decrypted status in vmbus_gpadl In CoCo VMs it is possible for the untrusted host to cause set_memory_encrypted() or set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues. In order to make sure callers of vmbus_establish_gpadl() and vmbus_teardown_gpadl() don't return decrypted/shared pages to allocators, add a field in struct vmbus_gpadl to keep track of the decryption status of the buffers. This will allow the callers to know if they should free or leak the pages.

CVE-2022-31162

Slack Morphism is an async client library for Rust. Prior to 0.41.0, it was possible for Slack OAuth client information to leak in application debug logs. Stricter and more secure debug formatting was introduced in v0.41.0 for OAuth secret types to reduce the possibility of printing sensitive information in application logs. As a workaround, do not print/output requests and responses for OAuth and client configurations in logs.

CVE-2022-39292

Slack Morphism is a modern client library for Slack Web/Events API/Socket Mode and Block Kit. Debug logs expose sensitive URLs for Slack webhooks that contain private information. The problem is fixed in version 1.3.2 which redacts sensitive URLs for webhooks. As a workaround, people who use Slack webhooks may disable or filter debug logs.
