CVE-2024-28987 is a critical vulnerability identified in the SolarWinds Web Help Desk (WHD) software. This flaw involves hardcoded credentials, allowing remote unauthenticated attackers to gain unauthorized access to the WHD system. Given its CVSS score of 9.1, the vulnerability poses a severe risk to organizations, potentially leading to data breaches and system compromise.
Targeted Sectors and Countries
The vulnerability CVE-2024-28987 has been primarily targeted by threat actors in sectors such as government, finance, healthcare, and critical infrastructure. Countries experiencing significant targeting include the United States, United Kingdom, Canada, Australia, and several European nations. The critical nature of the SolarWinds Web Help Desk software in supporting IT operations makes it a high-value target for cybercriminals and state-sponsored actors.
CVE-2024-28987 - Technical Information
Vulnerability Overview:
CVE ID: CVE-2024-28987
CVSS Score: 9.1 (Critical)
Affected Product: SolarWinds Web Help Desk (WHD)
Vulnerability Type: Hardcoded Credential
Date of Disclosure: August 23, 2024
The vulnerability arises from embedded hardcoded credentials within the SolarWinds Web Help Desk software. These credentials can be exploited by remote, unauthenticated attackers to gain access to the system. Once inside, attackers can navigate the WHD environment, potentially accessing sensitive data, modifying configurations, or even executing malicious scripts.
Technical Details:
The presence of hardcoded credentials in software is a significant security risk. Typically, developers embed these credentials for maintenance or debugging purposes. However, if these credentials are discovered by malicious actors, they can be used to bypass authentication mechanisms entirely. In the case of CVE-2024-28987, the credentials provide full administrative access, allowing attackers to control the help desk system entirely.
The vulnerability is particularly concerning because it does not require user interaction or special conditions to be exploited. An attacker with knowledge of the credentials can initiate an attack remotely, making it critical for organizations to address this issue immediately.
Exploitation in the Wild
Reports and threat intelligence sources indicate active exploitation of this vulnerability by sophisticated threat actors. Incidents have been observed where attackers utilized the hardcoded credentials to gain unauthorized access to internal help desk systems. These intrusions have led to data exfiltration, system modifications, and, in some cases, the deployment of malware to further compromise the network.
Indicators of Compromise (IOCs) include:
Unusual login attempts from unfamiliar IP addresses.
Unauthorized changes to help desk system configurations.
Sudden spikes in network traffic associated with the help desk server.
Presence of known malware signatures linked to this exploit.

APT Groups Using This Vulnerability
While specific Advanced Persistent Threat (APT) groups exploiting CVE-2024-28987 have not been disclosed publicly, the nature of the vulnerability makes it an attractive target for state-sponsored actors and sophisticated cybercriminal organizations.
APT groups typically target sectors such as government, finance, healthcare, and critical infrastructure. Given the critical functionality of the SolarWinds Web Help Desk software in supporting IT operations, it is crucial for organizations in these sectors to remain vigilant and proactive in their cybersecurity efforts.
Affected Product Versions
The affected versions of SolarWinds Web Help Desk are:
SolarWinds Web Help Desk versions up to 12.8.3 Hotfix 1
It is imperative for organizations using these versions to assess their systems and apply the necessary updates to mitigate the risk.
Workaround and Mitigation
Apply Patches: SolarWinds has released a hotfix to address this vulnerability. Administrators should immediately apply the latest updates to the Web Help Desk software.
Change Default Credentials: Ensure that any default or hardcoded credentials are changed to strong, unique passwords. This step is critical to prevent unauthorized access.
Monitor Network Traffic: Implement network monitoring to detect any unusual or unauthorized access attempts. Tools like Wireshark and Splunk can be invaluable in identifying suspicious activities.
Access Controls: Strengthen access controls to limit who can access the Web Help Desk system. Utilize role-based access controls (RBAC) and ensure that permissions are granted based on the principle of least privilege.
Incident Response Plan: Have an incident response plan in place to quickly address any potential breaches resulting from this vulnerability. Regularly update and test your incident response procedures.
