Overview

The vulnerability CVE-2025-8194 pertains to a defect found in the “tarfile” module of CPython, affecting the “TarFile” extraction and entry enumeration APIs. This vulnerability can lead to a system deadlock, triggered by the incorrect handling of tar archives with negative offsets. This poses a significant risk to any system or application using the affected versions of CPython, potentially leading to unauthorized system access, data leakage, or even full system compromise.

Vulnerability Summary

CVE ID: CVE-2025-8194
Severity: High (7.5 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

CPython | All versions prior to patch

How the Exploit Works

The exploit takes advantage of a flaw in the tarfile module of CPython. When processing tar archives with negative offsets, the tar implementation enters an infinite loop, resulting in a deadlock. This can be leveraged by an attacker to craft a malicious tar archive that, when processed, would cause the system or application to hang indefinitely. This could potentially allow for further malicious activity, such as unauthorized system access or data leakage.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited:

import tarfile
def malicious_archive():
with tarfile.open("malicious.tar", "w") as tar:
# Create a tarinfo object with negative offset
info = tarfile.TarInfo(name="malicious_file")
info.offset = -99999
# Add the malicious tarinfo object to the tar archive
tar.addfile(info)
# Execute the function to create the malicious archive
malicious_archive()

This code creates a tar archive containing a file with a negative offset. When this archive is processed by the affected versions of CPython, it would trigger the infinite loop and deadlock.

Affected Products

Product | Affected Versions

PHPGurukul Student Result Management System | v2.0

How the Exploit Works

The exploit takes advantage of an improper session invalidation mechanism in the /srms/change-password.php component of the application. By manipulating the session tokens, an attacker could potentially hijack a user’s session. This could grant the attacker unauthorized access to the system under the guise of a legitimate user, leading to unauthorized data access or even system compromise.

Conceptual Example Code

Consider the following conceptual HTTP request that an attacker might use:

GET /srms/change-password.php?session_id=VULNERABLE_SESSION_ID HTTP/1.1
Host: target.example.edu

In this example, the attacker is attempting to access the change-password.php page using a session ID that they have either guessed, stolen, or otherwise obtained illicitly. If the session invalidation is not handled correctly, this could allow the attacker to hijack the session associated with that ID, effectively impersonating the legitimate user.

Severity: High (7.5 CVSS)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

IBM Informix Dynamic Server | 12.10
IBM Informix Dynamic Server | 14.10

How the Exploit Works

The exploit takes advantage of the inadequate account lockout settings in IBM Informix Dynamic Server. Without appropriate lockout mechanisms, an attacker can engage in a brute force attack, systematically trying all possible combinations for account credentials until successful. This vulnerability can be exploited remotely, without any user interaction.

Conceptual Example Code

Below is a conceptual example of how this vulnerability might be exploited.

for password in `cat dictionary.txt`
do
echo Trying password: $password
curl --data "username=admin&password=$password" http://target.example.com/login
if [ "$?" -eq "0" ]; then
echo "Found password: $password"
break
fi
done

In this example, the attacker uses a script to go through a list of common passwords (`dictionary.txt`). The script sends HTTP POST requests with the username and password to the login endpoint of the target server. If the server responds with a success message, the script halts and the password is found.

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation, configured to detect and block multiple failed login attempts within a certain period of time.
