    Impact: Potential system compromise or data leakage

    Affected Products

    Product | Affected Versions

    Tcpreplay’s Tcprewrite | All versions prior to patch

    How the Exploit Works

    The exploit takes advantage of a double free vulnerability in the dlt_linuxsll2_cleanup() function within the tcpreplay’s tcprewrite. The vulnerability is triggered when tcpedit_dlt_cleanup() indirectly invokes the cleanup routine multiple times on the same memory region. By supplying a specifically crafted pcap file to the tcprewrite binary, an attacker can cause memory corruption, leading to a Denial of Service (DoS).

    Conceptual Example Code

    The following is a conceptual example of how the vulnerability might be exploited. This example uses a shell command to feed a malicious pcap file to the tcprewrite binary:

    ./tcprewrite --infile=malicious.pcap --outfile=clean.pcap --dlt=EN10MB --enet-dmac=00:11:22:33:44:55 --enet-smac=66:77:88:99:aa:bb

    In this example, “malicious.pcap” is a pcap file crafted to exploit the double free vulnerability in the tcprewrite.

    Mitigation

    Affected users should apply vendor patches as soon as they become available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used as temporary mitigation against potential attacks exploiting this vulnerability.

    Product | Affected Versions

    Vasion Print Virtual Appliance Host | Prior to 22.0.951
    Vasion Print Application (VA and SaaS deployments) | Prior to 20.0.2368

    How the Exploit Works

    The vulnerability arises from an undocumented local user account named ‘ubuntu’ with a preset password and a sudoers entry that grants this account passwordless root privileges. Anyone who knows the hardcoded password can obtain root privileges via local console or equivalent administrative access, thus enabling local privilege escalation. Although a patch for this vulnerability was reported, it is incomplete as it only remediated /etc/shadow, leaving /etc/sudoers still vulnerable.

    Conceptual Example Code

    The following is a conceptual example of how the vulnerability might be exploited. This example assumes that the attacker has gained local console or equivalent administrative access.

    $ ssh ubuntu@target.example.com  // Log in to the target system using the ubuntu account
    Password: [hardcoded password]  // Enter the hardcoded password
    $ sudo su  // Use sudo to switch to the root user, no password required due to the sudoers entry
    # whoami  // Verify that the current user is root
    root

    Once root access is gained, the attacker can execute any command, potentially leading to system compromise or data leakage.

    Affected Products

    Product | Affected Versions

    Vasion Print Virtual Appliance Host | Unconfirmed
    Vasion Print Application (Windows client deployments) | Unconfirmed

    How the Exploit Works

    The vulnerability exists due to the insecure handling of temporary files by the PrinterInstallerClient components of Vasion Print. The software creates files with NT AUTHORITY\SYSTEM privileges in a directory under the control of the local user. An attacker can exploit this by placing symbolic links or influencing filenames in the directory, causing the service to follow the link and write to arbitrary filesystem locations as SYSTEM. This allows a local, unprivileged user to overwrite or create files as SYSTEM, leading to a privilege escalation.

    Conceptual Example Code

    The following is a conceptual example of how the vulnerability might be exploited:

    # Create a symbolic link to a protected file
    ln -s /protected/system_file /Users/%USER%/AppData/Local/Temp/temp_file
    # Wait for the service to write to the temp file
    # This will overwrite the protected file due to the symbolic link

    This conceptual code demonstrates how an attacker might create a symbolic link to a protected file and use this vulnerability to overwrite it, leading to a privilege escalation.

    How the Exploit Works

    The vulnerability stems from a flaw in the PrinterInstallerClientService’s administrative operations. The service requires root privileges for certain tasks, but these checks rely on calls to geteuid(). By preloading a malicious shared object that overrides geteuid(), an attacker can trick the service into thinking it’s running with root privileges, thereby bypassing authentication. This action allows the attacker to execute administrative commands and potentially compromise the system or leak data.

    Conceptual Example Code

    Consider the following shell command as a conceptual example of how this vulnerability might be exploited:

    # Set LD_PRELOAD to a malicious shared object containing a geteuid() override
    export LD_PRELOAD=/path/to/malicious.so
    # Run PrinterInstallerClientService, which will now execute with (fake) root privileges
    ./PrinterInstallerClientService

    Please note, this is a conceptual example and should not be used for any malicious purposes. It is only intended to convey the nature of the exploit and is not a working exploit code.

The flaw lies in the local inter-process communication (IPC) mechanism that can be exploited by a local attacker to hijack user sessions and perform unauthorized actions. This poses a significant threat to system integrity and data confidentiality.

    Vulnerability Summary

    CVE ID: CVE-2025-34189
    Severity: High (7.8 CVSS Score)
    Attack Vector: Local
    Privileges Required: Low
    User Interaction: None
    Impact: Unauthorized actions in user sessions, potential system compromise, and data leakage

    Affected Products

    Product | Affected Versions

    Vasion Print Virtual Appliance Host | Versions prior to 1.0.735
    Vasion Print Application (macOS/Linux client deployments) | Versions prior to 20.0.1330

    How the Exploit Works

    The vulnerability stems from the misuse of IPC mechanism. IPC request and response files are stored inside /opt/PrinterInstallerClient/tmp, which have world-readable and world-writable permissions. Therefore, any local user can craft malicious request files, which when processed by privileged daemons, can lead to unauthorized actions being performed in other user sessions.

    Conceptual Example Code

    Below is a conceptual shell command an attacker might use to exploit this vulnerability:

    echo "{malicious_command: '...'}" > /opt/PrinterInstallerClient/tmp/request-file

    This command creates a request file with a malicious command in the location that is processed by privileged daemons, leading to the potential execution of unauthorized actions.

    Affected Products

    Product | Affected Versions

    Vasion Print Virtual Appliance Host | versions prior to 1.0.735
    Vasion Print Application (macOS/Linux client deployments) | versions prior to 20.0.1330

    How the Exploit Works

    The vulnerability lies in the local logging mechanism of the affected Vasion Print systems. Authentication session tokens, including PHPSESSID, XSRF-TOKEN, and laravel_session, are stored in plaintext within world-readable log files. Any local user with access to the server hosting these logs can extract these session tokens. Once obtained, these tokens can be used to authenticate remotely to the SaaS environment, bypassing the standard login procedure. This can potentially lead to unauthorized system access and exposure of sensitive information.

    Conceptual Example Code

    Here is a conceptual example of how this vulnerability might be exploited:

    # Access the log file
    cat /path/to/logfile.log
    # Look for session tokens
    grep -o -P '(?<=PHPSESSID:).*(?=,)' logfile.log
    grep -o -P '(?<=XSRF-TOKEN:).*(?=,)' logfile.log
    grep -o -P '(?<=laravel_session:).*(?=,)' logfile.log
    # Use the extracted tokens to authenticate
    curl -H 'Cookie: PHPSESSID=extracted_token; XSRF-TOKEN=extracted_token; laravel_session=extracted_token' https://target-saas-env.com

    This code block is a conceptual example and does not represent an actual exploit. It demonstrates the process of extracting session tokens from log files and using them to bypass normal authentication procedures.
