CISA Urges All Organizations to Patch Exploited Critical Ivanti Flaws

CVE-2024-13159 is an absolute path traversal vulnerability (CWE-36) in Ivanti Endpoint Manager (EPM) that allows a remote, unauthenticated attacker to leak sensitive information from the server. It is triggered when the EPM server processes attacker-supplied requests containing absolute file-system paths without properly constraining them, letting the attacker retrieve files outside the intended directory. A successful attack discloses arbitrary file contents, which could include configuration or credential material useful for further compromise; the available data describes information disclosure only, not code execution. Any organization running an Ivanti EPM management server, particularly one reachable by untrusted networks, is affected, though the source data does not specify affected version ranges. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2025-03-10, indicating confirmed in-the-wild exploitation, and EPSS assigns it a 100% probability of exploitation within 30 days; no public proof-of-concept is known.

Do: Apply the fixed updates identified in Ivanti's security advisory (specific patched versions are not included in the available data), and follow CISA KEV required action: apply vendor mitigations, comply with BOD 22-01 guidance for cloud services, or discontinue use if mitigations are unavailable. Until patched, restrict network access to the EPM management server to trusted networks and review HTTP/server logs for requests referencing absolute file paths that could indicate exploitation.

Advantive VeraCore, a warehouse management and order fulfillment platform, contains an unrestricted file upload flaw (CWE-434) in its upload.aspx endpoint that fails to properly restrict what files can be uploaded and where they are stored. A remote attacker with no credentials can abuse the endpoint to write files into unintended, attacker-influenced folders on the server. By placing crafted files (for example, script files) into web-reachable directories, an attacker can typically escalate an arbitrary upload into webshell deployment and code execution on the hosting server. Any organization running VeraCore, especially instances with the upload endpoint reachable from the internet, is exposed. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2025-03-10, indicating active exploitation, and EPSS assigns a 32.3% probability of exploitation within 30 days (98th percentile).

Do: Apply the mitigations required under CISA KEV/BOD 22-01, following Advantive's instructions, and contact the vendor for the fixed release since no patched version is specified in the available data. In the interim, restrict network access to upload.aspx (allow only trusted users or VPN/internal traffic), enforce file-type and destination validation at a WAF/reverse proxy where possible, and hunt for unexpected or recently modified files in VeraCore's web directories plus suspicious entries in web access logs to detect webshells or uploaded payloads.

Ivanti Cloud Services Appliance versions 4.6 Patch 518 and before contain an OS command injection flaw (CWE-78) that allows a remote, authenticated attacker to achieve remote code execution. The attacker must already hold administrator-level privileges on the appliance, and exploitation is triggered by sending crafted input to the appliance over the network. Successful exploitation yields arbitrary command execution on the CSA, and related reporting indicates nation-state actors have been exploiting Ivanti CSA flaws for network infiltration, including attacks on French government and telecom targets. Only organizations still running CSA 4.6.x are affected, and that product line has reached end-of-life and will not receive further security updates. The vulnerability was added to CISA's Known Exploited Vulnerabilities catalog on 2024-09-13 and carries a very high EPSS score (88.5%, 100th percentile), signaling confirmed and likely ongoing exploitation in the wild.

Do: Because CSA 4.6.x has reached end-of-life, remove CSA 4.6.x from service or migrate to the supported 5.0.x line, as future 4.6.x flaws are unlikely to receive fixes. Given confirmed nation-state exploitation, hunt for signs of compromise such as unexpected admin sessions, processes, or network tunnels, and restrict internet exposure of any remaining 4.6.x appliances in the interim.

CVE-2024-8963 is a path traversal vulnerability (CWE-22) in the Ivanti Cloud Services Appliance (CSA), a virtual appliance used to remotely manage Ivanti Endpoint Manager environments. A remote, unauthenticated attacker can send crafted requests containing directory traversal sequences to reach restricted functionality without any credentials. Successful exploitation grants access to restricted (including administrative) functions on the appliance, and public reporting indicates it has been chained with other CSA zero-day flaws by nation-state attackers to infiltrate networks. All CSA 4.6.x releases before Patch 519 are affected, and the 4.6.x product line has reached end-of-life, meaning future 4.6.x vulnerabilities will not receive fixes. Exploitation is confirmed in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2024-09-19, and multiple outlets report Chinese-linked actors exploiting CSA zero-days against French government, telecom and other critical-infrastructure targets.

Do: Upgrade CSA 4.6.x to Patch 519 or later, or move to the supported 5.0.x line; because 4.6.x is end-of-life, CISA urges removing CSA 4.6.x from service or migrating to 5.0.x rather than relying on future 4.6.x patches. Until patched, restrict or remove internet exposure of CSA appliances and review logs for unauthenticated access to restricted functionality, since this flaw is being chained with other CSA vulnerabilities in targeted intrusions.

CVE-2024-9380 is an OS command injection flaw (CWE-77/CWE-78) in the admin web console of Ivanti Cloud Services Appliance (CSA), fixed in version 5.0.2. A remote attacker who is already authenticated with administrative privileges can inject arbitrary operating system commands through the console, which the appliance then executes. Successful exploitation yields remote code execution with high impact on confidentiality, integrity, and availability (CVSS 3.1: 7.2). All CSA releases before 5.0.2 are affected, and the widely deployed 4.6.x line has reached End-of-Life, so EOL users must remove it from service or move to 5.0.x or later. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2024-10-09, and contemporaneous reporting describes Chinese nation-state actors exploiting Ivanti CSA zero-days against French government and telecom targets, with a 63.2% EPSS probability of exploitation in the next 30 days (99th percentile).

Do: Upgrade Ivanti CSA to 5.0.2 or later; if you are running the End-of-Life 4.6.x line, either remove it from service or migrate to the supported 5.0.x line, per CISA's KEV required action. Restrict exposure of the admin web console (do not leave it directly internet-facing) and verify whether your appliance was targeted. Given reported nation-state exploitation of CSA zero-days, review appliance logs and admin credentials for signs of compromise.

CVE-2025-0282 is a stack-based buffer overflow (CWE-121) in Ivanti Connect Secure, Policy Secure, and ZTA Gateways, reachable by unauthenticated network input. An attacker can trigger it remotely by sending crafted, unauthenticated traffic to a vulnerable gateway, overwriting stack memory and gaining code execution under the appliance's context. Successful exploitation yields unauthenticated remote code execution on the device, giving the attacker control of the VPN/secure-access gateway and a foothold into the protected network. Organizations running any of the affected Ivanti secure-access products are exposed; the source data specifies no version ranges, so defenders should consult Ivanti's advisory for exact affected and fixed releases. The flaw is being actively exploited: it was added to CISA KEV on 2025-01-08 with known ransomware use, and EPSS assigns a 100% probability of exploitation within 30 days (100th percentile), despite no public PoC being known.

Do: Apply the patched releases identified in Ivanti's advisory and follow CISA's required action: hunt for signs of compromise, remediate if indicators are found, and apply updates before returning any device to service. Because exploitation is active and ransomware use is known, treat any appliance that was internet-reachable before patching as potentially compromised (check integrity, rotate credentials). Exact fixed versions were not included in the source data, so verify the correct update path for your branch (including older Connect Secure/Policy Secure releases) against Ivanti's bulletin.
