Summary
OpenTelemetry eBPF Instrumentation: Privileged Java agent injection allows arbitrary host file overwrite via untrusted TMPDIR
Details

Summary

A flaw in the Java agent injection path allows a local attacker controlling a Java workload to overwrite arbitrary host files when Java injection is enabled and OBI is running with elevated privileges. The injector trusted TMPDIR from the target process and used unsafe file creation semantics, enabling both filesystem boundary escape and symlink-based file clobbering.

Remediation

Upgrade to https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/releases/tag/v0.8.0.

Details

The issue is in the Java agent staging logic in pkg/internal/java/java_inject.go.

The injector reads TMPDIR from the target process environment in findTempDir(...) and validates it with dirOK(...). In the vulnerable implementation, dirOK(...) used filepath.Join(root, dir), where root is /proc/<pid>/root. If dir is an absolute path, filepath.Join discards root, so values such as /etc or /proc/1/root/etc are resolved on the host instead of within the target process root.

That validated value is later reused in copyAgent(...) to build the destination path for the Java agent JAR. As a result, a malicious process can influence the privileged injector to write outside the intended /proc/<pid>/root boundary.

The file creation step further increases impact. The vulnerable code created the destination with os.OpenFile(..., os.O_WRONLY|os.O_CREATE|os.O_TRUNC, 0o644). Because this does not use exclusive creation or symlink protections, an attacker can pre-create a symlink at the chosen destination, for example in a writable temp directory, and cause the injector to truncate or overwrite another file writable by the privileged OBI process.

Relevant code paths:

  • pkg/internal/java/java_inject.go: findTempDir(...)
  • pkg/internal/java/java_inject.go: dirOK(...)
  • pkg/internal/java/java_inject.go: copyAgent(...)

In short, the vulnerability is caused by two issues acting together:

  1. Untrusted TMPDIR from the target process can escape the intended target root.
  2. The destination JAR is written with unsafe open semantics that allow clobbering via symlink or attacker-controlled destination selection.

PoC

Prerequisites:

  • OBI is running with elevated privileges on the host.
  • Java injection is enabled.
  • The attacker can run or control a Java process on the same host.

Reproduction outline for the path escape case:

  1. Start a Java process with a controlled environment variable such as:
  2. TMPDIR=/etc
  3. or TMPDIR=/proc/1/root/etc
  4. Ensure the process is discovered by OBI and selected for Java agent injection.
  5. Wait for the injector to stage the agent JAR.
  6. Observe that the injector attempts to write obi-java-agent.jar outside /proc/<pid>/root, under the attacker-controlled host path.

Reproduction outline for the symlink clobber case:

  1. Start a Java process with TMPDIR=/tmp or another writable temp directory.
  2. Before injection occurs, create a symlink at the expected destination:
  3. /tmp/obi-java-agent.jar -> /path/to/target/file
  4. Trigger Java agent injection for that process.
  5. Observe that the privileged injector opens the symlink target with truncate semantics and overwrites the linked file contents.

Code evidence:

  • findTempDir(...) reads ie.FileInfo.Service.EnvVars["TMPDIR"]
  • dirOK(...) validates using filepath.Join(root, dir)
  • copyAgent(...) writes the JAR into the selected temp directory
  • the vulnerable write uses os.OpenFile(..., os.O_WRONLY|os.O_CREATE|os.O_TRUNC, 0o644)

Impact

This is an arbitrary file overwrite / file clobber vulnerability in a privileged host component.

Affected users are deployments where:

  • Java injection is enabled
  • OBI runs with elevated privileges
  • untrusted local workloads can run Java processes on the same host

An attacker who can control a local Java process may be able to overwrite host files writable by OBI, which can lead to:

  • host integrity compromise
  • service disruption or denial of service
  • possible local privilege escalation depending on deployment details and overwritten targets

The issue is local rather than remote, but the impact is high because the vulnerable component operates with elevated privileges on the host.

8.4 (High)

Summary
Duplicate Advisory: Symlink escape in CorpusReader allows arbitrary local file read outside the corpus root
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-r6gq-whwq-mvg9. This link is maintained to preserve external references.

Original Description

NLTK versions before 3.9.4 contain a symlink escape vulnerability in CorpusReader.open() that allows local attackers to read arbitrary files outside the corpus root. The vulnerability exists because path validation is lexical and does not account for symlink resolution, enabling attackers to place symlinks inside the corpus root to access files outside the intended boundary.

Mitigation MIT-48.1
Architecture and Design

Strategy: Separation of Privilege

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack

An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.

CAPEC-17: Using Malicious Files

An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.

CAPEC-35: Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.

CAPEC-76: Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
