pwndbg_auxv
AI agents call pwndbg_auxv to retrieve information from Pwndbg Lldb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'auxv' command in pwndbg displays the auxiliary vector of a running process, which is information-retrieval only with no side effects. However, severity is elevated to 'high' because access to process internals (memory layout, ASLR state, architecture details) enables exploit development and information disclosure that could compromise system security if misused by an untrusted agent.
From the tool's definition Tool name 'pwndbg_auxv' suggests it reads auxiliary vector data from a debugged process, consistent with pwndbg's read-only inspection commands like 'pwndbg_backtrace' and 'pwndbg_argv' on the same server. The empty description prevents higher confidence.
Attacks that exploit this kind of access
pwndbg_auxv. It is categorised as a Read tool in the Pwndbg Lldb MCP Server, which means it retrieves data without modifying state.
Register the Pwndbg Lldb MCP server in PolicyLayer and add a rule for pwndbg_auxv: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Pwndbg Lldb. Nothing to install.
pwndbg_auxv is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the pwndbg_auxv rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for pwndbg_auxv. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
pwndbg_auxv is provided by the Pwndbg Lldb MCP server (micro-evaluation-group/pwndbg-lldb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
