CVE-2025-0283 is a high-severity vulnerability affecting Ivanti Connect Secure, Ivanti Policy Secure, and Ivanti Neurons for Zero Trust Access (ZTA). This vulnerability allows a local authenticated attacker to escalate their privileges due to a stack-based buffer overflow. The CVSS score for this vulnerability is 7, indicating a high level of risk that organizations must address promptly.
The potential for misuse of this vulnerability is significant, as it could lead to unauthorized access and control over affected systems. Organizations utilizing the impacted Ivanti products must take immediate action to patch their systems to prevent exploitation. Given the nature of the vulnerability, it is crucial for security teams to prioritize remediation efforts.
Published on January 8, 2025, this vulnerability has garnered attention due to its capability for local privilege escalation in widely deployed security products. Organizations should act swiftly to mitigate the risks associated with this vulnerability, especially in environments where these Ivanti products are critical.
As of now, there is no known public exploit for this vulnerability, but the potential for future exploitation exists. Organizations should remain vigilant and monitor for updates regarding this CVE. The urgency for defenders is high, and patching should be prioritized in the next scheduled maintenance cycle.
Vulnerability Details
The official description of CVE-2025-0283 states that a stack-based buffer overflow in Ivanti Connect Secure versions prior to 22.7R2.5, Ivanti Policy Secure versions prior to 22.7R1.2, and Ivanti Neurons for ZTA gateways versions prior to 22.7R2.3 allows a local authenticated attacker to escalate their privileges. This vulnerability falls under the CWEs CWE-121 (Stack-based Buffer Overflow) and CWE-787 (Out-of-bounds Write).
The CVSS score of 7 indicates that this vulnerability is classified as high severity. The attack vector is local, requiring an attacker to have local access to the system. The attack complexity is rated as high, requiring specific conditions to be met for exploitation. Privileges required are low, and user interaction is not necessary. The impacts on confidentiality, integrity, and availability are all rated high.
Technical Analysis
The root cause of this vulnerability is a stack-based buffer overflow that occurs when the software does not properly validate input sizes, allowing an attacker to write beyond the buffer's boundary. The attack vector is local, meaning that the attacker must have access to the system where the vulnerable software is running. The attack complexity is high, as it requires specific conditions or knowledge of the system's state.
Regarding privileges required, the attacker needs to have low privileges to execute the attack, which could lead to a situation where they can escalate their privileges to gain unauthorized access. User interaction is not required, making it easier for an attacker to exploit this vulnerability without needing assistance from the user.
The impacts of this vulnerability are significant; an attacker exploiting this vulnerability could potentially gain full control over the affected systems, compromising confidentiality, integrity, and availability. Organizations using Ivanti Connect Secure, Policy Secure, or Neurons for ZTA should evaluate their exposure to this vulnerability and implement necessary controls.
Risk & Impact Analysis
Organizations that utilize affected Ivanti products face considerable risks due to CVE-2025-0283. The potential for a local authenticated attacker to escalate privileges poses a significant threat, particularly in environments where sensitive data is processed or stored. The blast radius of such an attack can extend across the network, affecting multiple systems and applications.
Given the high CVSS score of 7, organizations should treat this vulnerability with urgency. The risk to organizations includes unauthorized access to critical systems, potential data breaches, and overall operational disruptions. Therefore, organizations should prioritize patching immediately as part of their risk management strategies.
The urgency for remediation is high, as attackers may leverage this vulnerability to gain unauthorized access. Organizations must ensure they are using the latest patched versions of Ivanti products to mitigate this risk effectively.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
