Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

UTT HiPER 840G | Up to 3.1.1-190328

How the Exploit Works

The vulnerability resides in an unknown function within the file /goform/getOneApConfTempEntry. By manipulating the tempName argument, attackers can trigger a buffer overflow condition. A buffer overflow occurs when more data is written into a block of memory, or buffer, than it can hold. This excess data then overflows into adjacent memory spaces, potentially overwriting other data or causing the system to crash. In this case, this vulnerability can be exploited by a remote attacker, allowing them to execute arbitrary code or cause a denial of service.

Conceptual Example Code

The following is a conceptual example illustrating how an attacker might exploit this vulnerability. This is not a real exploit, but a simplified representation to demonstrate the attack mechanism.
```
POST /goform/getOneApConfTempEntry HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "tempName": "A"*10000 }
```
In this example, the attacker is sending an unusually large amount of data “A”*10000 as the tempName argument in an attempt to cause a buffer overflow.

Recommendations

Users are strongly advised to apply the vendor patch as soon as it becomes available. In the meantime, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy.

CVE-2025-40925: Insecure Session ID Generation in Starch Versions 0.14 and Earlier
Overview

The vulnerability in question, CVE-2025-40925, is a serious security issue that affects Starch versions 0.14 and earlier. Starch, a popular software, is widely used for its session management capabilities. However, the way it generates session ids in the mentioned versions is insecure and potentially harmful to systems. This matters because session ids are critical for maintaining secure connections between users and applications. If these ids are predictable, it could provide an attacker with unauthorized access to systems, potentially leading to compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-40925
Severity: Critical (9.1 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Unauthorized access to systems, potential system compromise, or data leakage

Affected Products

Product | Affected Versions

Starch | 0.14 and earlier

How the Exploit Works

The insecure session id generation in Starch versions 0.14 and earlier is due to a combination of factors that make the ids predictable. The default session id generator returns a SHA-1 hash seeded with a counter, the epoch time, the built-in rand function, the PID, and internal Perl reference addresses. The PID comes from a small set of numbers and the epoch time can be guessed or leaked from the HTTP Date header. The built-in rand function, which is unsuitable for cryptographic usage, further weakens the security of the session id. An attacker could exploit this vulnerability by predicting the session id and gaining unauthorized access to a system.

Conceptual Example Code

Given the nature of this vulnerability, an exact exploit code would be complex and involve several steps, including predicting the PID, the epoch time, and the output of the rand function. However, a simplified conceptual example could be as follows:
```
# Assume this is a part of the attacker’s script
# Predict the epoch time
my $predicted_epoch_time = time;
# Predict the PID
my $predicted_pid = $$;
# Simulate the rand function
my $predicted_rand = rand();
# Generate the session id
my $session_id = sha1_hex($counter . $predicted_epoch_time . $predicted_rand . $predicted_pid . $perl_ref_addr);
# Use the predicted session id to send a request
```
In a real-world scenario, the attacker would need to overcome more complexities, like guessing the Perl reference addresses and the counter. The above script is a highly simplified representation of the potential attack.

Vulnerability Summary

CVE ID: CVE-2025-34191
Severity: High (8.4 CVSS Severity Score)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Potential full system compromise and data leakage

Affected Products

Product | Affected Versions

Vasion Print Virtual Appliance Host | Prior to 22.0.843
Vasion Print Applications (macOS/Linux) | Prior to 20.0.1923

How the Exploit Works

The vulnerability lies in the response file handling of the Vasion Print service. When tasks generate output, the service writes this response data into files under the directory ‘/opt/PrinterInstallerClient/tmp/responses/’ and uses the requested filename. The problem arises as the service follows symbolic links located in the responses directory and writes as the service user, which typically has root privilege. An unprivileged user could exploit this to cause the service to overwrite or create arbitrary files on the filesystem as root, thereby achieving local privilege escalation and potentially compromising the whole system.

Conceptual Example Code

The following is a conceptual example of how this vulnerability could be exploited:
```
# Create a symbolic link to a sensitive file
ln -s /etc/passwd /opt/PrinterInstallerClient/tmp/responses/mylink
# Trigger a task that generates output with the filename "mylink"
# The service would overwrite /etc/passwd with its output
```
This could potentially be used to modify critical configuration files, replace or inject malicious binaries, or perform other actions leading to full system compromise. Ensure to apply the necessary patches provided by the vendor or use Web Application Firewall (WAF) or Intrusion Detection Systems (IDS) as temporary mitigation.

Vasion Print Virtual Appliance Host | Prior to 25.2.169
Vasion Print Application | Prior to 25.2.1518

How the Exploit Works

The exploitation of this vulnerability is primarily based on the attacker’s ability to access the same external L2 segment or manipulate the appliance to function as a gateway for adding routes. This allows the attacker to directly reach the IP addresses of the containers, giving them unauthorized access to internal services such as HTTP APIs, Redis, MySQL, etc. These services are either unsecured or are prone to known exploitation chains, thus further enabling the attacker’s lateral movement within the system, executing remote code, exfiltrating data, or even a total system compromise.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. Note: this is a simplified example to illustrate the nature of the vulnerability and does not represent a real-world exploit.
```
# Attacker gains access to the same external L2 segment
route add -net <container IP range> gw <appliance IP>
# Using curl or similar tool to interact with exposed HTTP API
curl http://<container IP>:<port>/api/endpoint -d "malicious_payload"
```
This would allow the attacker to send a malicious payload directly to an exposed internal service, potentially leading to unauthorized actions within the system.

Mitigation Guidance

To mitigate the risks posed by this vulnerability, it is recommended to apply the vendor patch immediately. In cases where immediate application of the patch is not feasible, the use of Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) may serve as temporary mitigation. However, these are not long-term solutions and should only be used as a stop-gap until the patch can be applied.

How the Exploit Works

The vulnerability stems from the overly-permissive filesystem permissions associated with Docker containers in Vasion Print Virtual Appliance Host and Application. The software mounts host configuration and secret material under /var/www/efs_storage into numerous Docker containers. Consequently, files such as secrets.env, GPG-encrypted blobs in .secrets, MySQL client keys, and application session files become accessible from multiple containers.
If an attacker gains control over or access to any of these containers, they can read or modify these artifacts. This could lead to credential theft, Remote Code Execution (RCE) via Laravel APP_KEY, Portainer takeover, and ultimately a full compromise of the system.

Conceptual Example Code

This is a conceptual example of how an attacker might attempt to exploit this vulnerability.
```
# Command to list files in the Docker container
docker exec -it [container_id] ls /var/www/efs_storage
# Command to read sensitive files
docker exec -it [container_id] cat /var/www/efs_storage/secrets.env
```
In the above example, the attacker uses Docker commands to list and read sensitive files in the Docker container. This is a simplified representation and actual exploitation may involve more complex commands and manipulations.

Mitigation Guidance

To mitigate this vulnerability, it is recommended that organizations apply the vendor’s patch immediately. If this is not immediately possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation. However, these measures do not eliminate the vulnerability, and the patch should still be applied as soon as it becomes feasible.
Remember, staying vigilant and keeping systems up-to-date is an essential part of maintaining a strong cybersecurity posture.

Vasion Print Application (VA and SaaS deployments) | Prior to 20.0.1923

How the Exploit Works

The vulnerability resides in a script named `/var/www/app/resetroot.php`, which lacks necessary authentication checks. When this script is executed, it performs a SQL update that sets the database administrator username to ‘root’ and its password to the SHA-512 hash of the string ‘password. This can allow an attacker to reset the MySQL root password and gain full control over the database.
Additionally, a deserialization issue exists in the commented-out code in `/var/www/app/lib/common/oses.php`, which unserializes session data. If this code is re-enabled or reached with attacker-controlled serialized data, it can lead to remote code execution.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request to trigger the `resetroot.php` script:
```
GET /resetroot.php HTTP/1.1
Host: target.example.com
```
After running this command, the MySQL root password would be reset, allowing the attacker to login with `username: root` and `password: password`.

Impact and Mitigation

The impact of this vulnerability is significant, as it could lead to complete system compromise and potential data leakage. Therefore, it is crucial to immediately apply the vendor patch once released. Until the patch is available, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. Regular monitoring and logging of network activity can also assist in identifying any unusual or suspicious activities.

User Interaction: None
Impact: System compromise, data leakage

Affected Products

Product | Affected Versions

Vasion Print Virtual Appliance Host | All versions prior to patch
Vasion Print Application (SaaS deployments) | All versions prior to patch

How the Exploit Works

The vulnerability stems from the fact that the Docker containers in Vasion Print’s Virtual Appliance Host and Application run their primary application processes, such as PHP workers, Node.js servers, and custom binaries, as the root user. A potential attacker who manages to breach a single Docker container could thus gain root access to it.
Once inside, the attacker is free to move laterally within the compromised container and potentially exploit the host system. The security risk arises because many Docker containers share the same operating system kernel as the host, allowing the attacker to escalate privileges on the host system and potentially compromise it.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. Please note that this is a simplified representation and the actual attack may involve more intricate steps.
```
# After breaching the Docker container
$ whoami
> root
# Attempt to write to a system file
$ echo "malicious code" >> /etc/critical_system_file
```
In this example, the attacker has breached the Docker container and confirmed that they have root access. They then attempt to write to a critical system file, which should be restricted. However, because of the vulnerability, the write operation succeeds, potentially leading to a system compromise.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. Until then, deploying a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) may provide temporary mitigation. Regular monitoring of system logs and network traffic for any unusual activity can also help detect a potential exploit early.

Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

Vasion Print Virtual Appliance Host | Versions prior to 22.0.1002
Vasion Print Application | Versions prior to 20.0.2614

How the Exploit Works

The exploit takes advantage of the outdated, end-of-life, unsupported, or otherwise vulnerable third-party components present in the Docker containers of the affected versions of Vasion Print’s products. By leveraging these vulnerable components, an attacker can increase the product’s attack surface, enabling exploitation chains. This could lead to potential system compromise or data leakage, affecting the confidentiality, integrity, and availability of the system and data.

Conceptual Example Code

```
$ docker run -d --name exploit-container -v /var/run/docker.sock:/var/run/docker.sock malicious-image:latest
```
In this hypothetical scenario, an attacker is deploying a malicious Docker container (`malicious-image:latest`) on the target system. The attacker uses Docker’s `-v` option to bind-mount the host’s Docker socket into the container, effectively giving the malicious container control over the Docker daemon on the host system. This could potentially allow the attacker to manipulate the host system’s Docker containers, including those running the vulnerable versions of Vasion Print’s products.
