Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.

Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

No fix will be released: Ivanti CSA (Cloud Services Appliance) is end of life. Replace it, or isolate it from untrusted networks until you can.

Check the firmware or software version for Ivanti CSA (Cloud Services Appliance) in the device's admin interface against the vendor advisory.

As Ivanti CSA has reached End-of-Life status, users are urged to remove CSA 4.6.x from service or upgrade to the 5.0.x line of supported solutions, as future vulnerabilities on the 4.6.x version of CSA are unlikely to receive security updates.

Description

Path Traversal in the Ivanti CSA before 4.6 Patch 519 allows a remote unauthenticated attacker to access restricted functionality.

Impact

The exploitation of CVE-2024-8963 can have severe consequences for organizations using Ivanti CSA. Unauthorized access to restricted functionality can lead to exposure of sensitive configuration files, credentials, or other critical data, compromising confidentiality. Attackers might also alter system settings or execute unauthorized operations, impacting data integrity. While availability impact is rated low, the breach of trust and potential lateral movement within the network can lead to further attacks, including data exfiltration or disruption of cloud service management. Given Ivanti CSA's role in managing cloud services, a successful attack could undermine cloud infrastructure security, affecting business continuity and regulatory compliance. Organizations in sectors relying heavily on Ivanti CSA for cloud service orchestration, such as government, healthcare, finance, and large enterprises, face heightened risk. The vulnerability's remote and unauthenticated nature increases the attack surface, making widespread exploitation plausible if unpatched.

Mitigation

To mitigate CVE-2024-8963, organizations should: 1) Immediately apply the Ivanti CSA 4.6 Patch 519 or later once available to remediate the path traversal vulnerability. 2) Until patching is possible, restrict network access to the Ivanti CSA appliance by implementing firewall rules limiting connections to trusted management IPs only. 3) Employ network segmentation to isolate the appliance from general user networks and reduce exposure. 4) Monitor logs and network traffic for unusual path traversal patterns or unauthorized access attempts targeting the appliance. 5) Conduct a thorough audit of the appliance configuration and access controls to ensure no unauthorized changes have occurred. 6) Educate security teams about this vulnerability to enhance detection and response capabilities. 7) Consider deploying web application firewalls (WAFs) or intrusion prevention systems (IPS) with rules targeting path traversal attack signatures to provide an additional layer of defense. 8) Maintain up-to-date backups of critical configurations and data to enable recovery if compromise occurs.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
