Affected Products

Product | Affected Versions

Java | All versions prior to patch

How the Exploit Works

This vulnerability arises due to a logic error in the code of ContentProtectionTogglePreferenceController.java. Specifically, the updateState function incorrectly allows a secondary user to modify the primary user’s deceptive app scanning setting. An attacker exploiting this vulnerability can disable the primary user’s application scanning, potentially installing malicious applications without detection, thereby compromising the system’s security.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This pseudocode illustrates how a secondary user could potentially disable the primary user’s app scanning setting:

// Pseudo-code for exploiting CVE-2025-26435
SecondaryUser su = getSecondaryUser();
ContentProtectionTogglePreferenceController cptpc = getContentProtectionToggleController();
if (su.hasAccess(cptpc)) {
cptpc.updateState(false); // Disables deceptive app scanning for primary user
}

Mitigation Guidance

System administrators are strongly advised to apply the vendor patch as soon as it is available to mitigate this vulnerability. In the interim, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems should be configured to monitor and block suspicious activities and changes to user privileges.

Overview

The CVE-2025-26430 vulnerability presents a serious threat to system integrity and data confidentiality. It arises from a logic error in the getDestinationForApp function of SpaAppBridgeActivity, potentially enabling a cross-user file reveal. This can lead to a local escalation of privilege without any additional execution privileges necessary. Given that user interaction is not required for exploitation, the vulnerability is particularly dangerous and requires immediate attention.

Severity: High (7.8 CVSS score)
Attack Vector: Local
Privileges Required: None
User Interaction: Not required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

SpaAppBridgeActivity | All versions prior to patch

How the Exploit Works

The exploit targets the logic error in the getDestinationForApp function of SpaAppBridgeActivity. This error allows for a cross-user file reveal. An attacker can exploit this vulnerability to escalate privileges locally, without the need for any additional execution privileges. This means that an attacker could potentially access files and data that they would normally be restricted from, potentially leading to system compromise or data leakage.

Conceptual Example Code

Although there’s no specific exploit code, an attacker could potentially manipulate the logic error in the getDestinationForApp function. Here’s a conceptual example of how this might occur, using pseudocode:

def exploit():
# Instantiate SpaAppBridgeActivity object
app = SpaAppBridgeActivity()
# Manipulate the faulty getDestinationForApp method
app.getDestinationForApp("malicious_payload")

It’s important to note that the actual exploitation process would likely be far more complex and would require extensive knowledge of the affected system’s architecture and the specific implementation of the SpaAppBridgeActivity code.

Overview

The CVE-2025-36905 vulnerability is a critical flaw found in the gxp_mapping_create function of the gxp_mapping.c file, allowing potential privilege escalation due to a logic error.

Vulnerability Summary

CVE ID: CVE-2025-36905
Severity: High, CVSS Score 7.8
Attack Vector: Local
Privileges Required: None
User Interaction: Not Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

gxp_mapping.c | All versions prior to patch

How the Exploit Works

The vulnerability occurs due to a logic error in the gxp_mapping_create function of the gxp_mapping.c file. An attacker can exploit this flaw to escalate their privileges within the system, bypassing the normal privilege checks that the system has in place. This can be done locally without any additional execution privileges or user interaction, making it a serious threat.

Conceptual Example Code

Here’s a conceptual example of how an attacker might take advantage of this vulnerability:

#include <stdio.h>
#include "gxp_mapping.h"
int main() {
// Create an object with escalated privileges
struct gxp_mapping *gxp = gxp_mapping_create();
// Exploit the logic error to gain escalated privileges
gxp->privilege = "root";
// Execute a command with escalated privileges
system_with_privilege("rm -rf /", gxp);
}

This is a hypothetical example, but it illustrates the kind of danger this vulnerability poses. An attacker could potentially execute any command with escalated privileges, leading to total system compromise.

Mitigation Guidance

The best way to protect against this vulnerability is to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Regularly monitor and update your systems to protect against such vulnerabilities.

Overview

CVE-2025-36903 is a critical security vulnerability that potentially allows an attacker to perform an out-of-bounds read/write operation due to improper input validation. This vulnerability is particularly concerning as it can lead to a local escalation of privilege, potentially compromising system security and leading to data leakage. User interaction is not necessary for the exploitation of this vulnerability, increasing its potential impact.

Vulnerability Summary

CVE ID: CVE-2025-36903

Attack Vector: Local
Privileges Required: None
User Interaction: Not Required
Impact: Local escalation of privileges leading to potential system compromise and data leakage

Affected Products

Product | Affected Versions

lwis_io | All prior to version x.y.z

How the Exploit Works

The vulnerability arises from the lwis_io_buffer_write function, which fails to properly validate input data. This failure can allow an attacker to initiate an out-of-bounds (OOB) read/write operation. These operations can access or modify data that is outside the intended boundary of a buffer, leading to corruption of relevant data, a crash, or code execution. In this case, the OOB operation could lead to local escalation of privileges.

Conceptual Example Code

Below is a conceptual example of an exploit. The malicious payload is designed to trigger the OOB operation, taking advantage of the improper input validation.

$ ./lwis_io_buffer_write --input "malicious_payload"

This example is purely conceptual. The “malicious_payload” would be specifically crafted to exploit the OOB vulnerability.

Mitigation Measures

Users are advised to apply the vendor patch as soon as it becomes available. If the patch is not yet available or cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.

How the Exploit Works

The CVE-2025-36898 exploit takes advantage of a logic error in the code. A malicious actor with local access to the system can manipulate specific functions or processes due to this error, escalating their privileges on the system. This escalated access can allow the actor to execute commands, alter system configurations, or access sensitive data, leading potentially to system compromise or data leakage.

Conceptual Example Code

The following is a conceptual example of how this vulnerability might be exploited by a malicious actor. Note that this is a simplification and the actual exploit code may vary.

#!/bin/bash
# This is a conceptual example. Actual exploit would depend on the specific logic error.
# Gain local access
ssh user@target.com
# Exploit the logic error
# This below line is very much dependent on the actual vulnerability and is just a placeholder
./vulnerable_process --exploit-logic-error
# If successful, the attacker now has escalated privileges
whoami # Should return 'root' or other privileged user

Overview

The vulnerability, CVE-2025-36887, is a potentially serious security flaw that resides in the wl_cfgscan_update_v3_schedscan_results() function of wl_cfgscan.c. It could potentially allow an attacker to escalate local privileges due to an incorrect bounds check, leading to an out of bounds write. It is critical because it allows system compromise or data leakage without the need for any additional user interaction, making it a stealthy and dangerous threat.

Vulnerability Summary

CVE ID: CVE-2025-36887
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Local Privilege Escalation leading to potential system compromise or data leakage

Affected Products

Product | Affected Versions

wl_cfgscan.c | All versions prior to the vendor patch

How the Exploit Works

The vulnerability stems from an incorrect bounds check in the wl_cfgscan_update_v3_schedscan_results() function of wl_cfgscan.c. The faulty bounds check allows an out of bounds write to occur, which can be exploited to escalate local privileges. An attacker could leverage this flaw to gain elevated privileges on the system, potentially leading to full system compromise or data leakage.

Conceptual Example Code

This is an example shell command that a local attacker might use to exploit the vulnerability. Note that the real exploit would involve much more complex code, and this is just a conceptual illustration:

$ echo 'malicious_payload' > /path/to/vulnerable/wl_cfgscan.c

This command writes a malicious payload to the vulnerable wl_cfgscan.c file, exploiting the incorrect bounds check to trigger an out of bounds write, and potentially escalating the attacker’s privileges on the system.
Please note that this is a conceptual example and the actual exploit may vary depending upon the attacker’s skill, the system’s configuration and the nature of the malicious payload.
