#vulnerability

## Summary A critical remote OS command injection vulnerability has been identified in the Llama Factory training process. This vulnerability arises from improper handling of user input, allowing malicious actors to execute arbitrary OS commands on the host system. The issue is caused by insecure usage of the `Popen` function with `shell=True`, coupled with unsanitized user input. Immediate remediation is required to mitigate the risk. ## Affected Version Llama Factory versions **<=0.9.0** are affected by this vulnerability. ## Impact Exploitation of this vulnerability allows attackers to: 1. Execute arbitrary OS commands on the server. 2. Potentially compromise sensitive data or escalate privileges. 3. Deploy malware or create persistent backdoors in the system. This significantly increases the risk of data breaches and operational disruption. ## Root Cause The vulnerability originates from the training process where the `output_dir` value, obtained from the user input, is in...

In a sign of the times, a backdoor malware whose ancestors date back to 2005 has morphed to target Linux systems.

This Metasploit module leverages an unauthenticated remote command execution vulnerability in Ivanti's EPM Agent Portal where an RPC client can invoke a method which will run an attacker-specified string on the remote target as NT AUTHORITY\SYSTEM. This vulnerability is present in versions prior to EPM 2021.1 Su4 and EPM 2022 Su2.

Judge0 does not account for symlinks placed inside the sandbox directory, which can be leveraged by an attacker to write to arbitrary files and gain code execution outside of the sandbox.

Ubuntu Security Notice 7091-2 - USN-7091-1 fixed several vulnerabilities in Ruby. This update provides the corresponding update for ruby2.7 in Ubuntu 20.04 LTS. It was discovered that Ruby incorrectly handled parsing of an XML document that has specific XML characters in an attribute value using REXML gem. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service. This issue only affected in Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. It was discovered that Ruby incorrectly handled parsing of an XML document that has many entity expansions with SAX2 or pull parser API. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service. It was discovered that Ruby incorrectly handled parsing of an XML document that has many digits in a hex numeric character reference. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service.

The future of cybersecurity isn't about preventing every breach — it's about learning and growing stronger with each attack.
