TantoSec published a working exploit chaining a Telerik UI padding oracle to unauthenticated RCE; Progress patched the flaws in July.
TantoSec's Marcio Almeida released a full exploit chain and tooling for the RadAsyncUpload control in Telerik UI for ASP.NET AJAX, turning a padding oracle (CVE-2026-13182) into unauthenticated RCE via an unguarded type-resolution flaw (CVE-2026-13181, CVSS 8.1). Exploitation requires a rendered RadAsyncUpload handler and an explicit non-default encryption key, and took roughly 127,000 oracle requests (about an hour) in lab testing. Versions 2010.1.309 through 2026.2.519 are affected; Progress fixed the chain in 2026.2.708 on July 8, 2026, and no in-the-wild exploitation has been confirmed. A separate RCE chain in RadPersistenceManager and RadDockLayout (CVE-2026-13185, -13186, -13190) was also patched but has no public exploit.
Cyble argues supply chain attacks are a primary breach vector, citing Verizon DBIR third-party figures and CISA SBOM guidance to pitch its TPRM platform.
Cyble's vendor blog frames third-party compromise as a first-order breach risk, citing Verizon's 2026 DBIR finding that third parties were involved in 48% of breaches, up 60% year over year. It recounts the Cl0p campaigns against Progress MOVEit Transfer (CVE-2023-34362), which affected over 2,700 organizations and 93 million people, and Fortra GoAnywhere (CVE-2023-0669) with roughly 130 claimed victims. It also highlights CISA and NSA's 2026 Minimum Elements for a Software Bill of Materials covering open-source, AI, and SaaS components. The piece concludes by promoting Cyble's Third-Party Risk Management platform.

Unauthenticated OS Command Injection RCE in Progress Kemp LoadMaster
Progress Kemp LoadMaster, the application delivery controller/load balancer sold by Progress Software (formerly Kemp), contains an unauthenticated OS command injection flaw (CWE-77) in its API: unsanitized input sent to multiple command endpoints allows arbitrary operating-system commands to be executed on the appliance. Because the affected endpoints require no authentication, any remote attacker with network access to the appliance's API or management interface can trigger the bug directly; public research by WatchTowr describes it as a pre-authentication RCE chain (involving uninitialized memory/quote handling) that can yield root-level command execution. Successful exploitation gives an attacker full control of the appliance, consistent with the Critical 9.8 CVSS 3.1 score (network-exploitable, no privileges or user interaction, high impact on confidentiality, integrity and availability). Organizations running Progress Kemp LoadMaster appliances are affected, especially those where the management or API interface is reachable from the internet. Exploitation is confirmed and ongoing: CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-07 after 792 reported exploit attempts, and EPSS assigns a 99.6% probability of exploitation within 30 days.

Unauthenticated .NET Deserialization RCE in Progress Telerik UI for ASP.NET AJAX
CVE-2019-18935 is a .NET deserialization flaw (CWE-502) in the RadAsyncUpload function of Progress Telerik UI for ASP.NET AJAX through version 2019.3.1023. It is triggered when an attacker who knows the Telerik upload encryption keys — most commonly because the earlier flaws CVE-2017-11317 or CVE-2017-11357 exposed them, though keys can be obtained by other means — sends crafted serialized data to RadAsyncUpload, allowing remote code execution without authentication. Successful exploitation gives an attacker arbitrary code execution on the hosting IIS/ASP.NET web server, reflected in the critical 9.8 CVSS score. Any web application built with Telerik UI for ASP.NET AJAX at or below 2019.3.1023 is affected, unless 2019.3.1023 has the non-default hardening setting enabled (as of 2020.1.114 a default setting prevents the exploit). Exploitation is rampant in the wild: the flaw was added to CISA KEV on 2021-11-03 with known ransomware use, carries a 99.7% EPSS probability of exploitation, has multiple public exploits (Bishop Fox, RAU_crypto, noperator), and has been used by multiple threat groups — including ransomware and government-linked actors — to breach organizations including a U.S. federal agency.

Unauthenticated SQL Injection in Progress MOVEit Transfer
CVE-2023-34362 is an unauthenticated SQL injection flaw (CWE-89) in Progress MOVEit Transfer that allows an attacker with no credentials to gain unauthorized access to the product's database. It is triggered remotely via crafted input submitted to the MOVEit Transfer web application, with the impact varying by the backend database engine in use (MySQL, Microsoft SQL Server, or Azure SQL). A successful attacker can infer the structure and contents of the database and, depending on the engine, execute SQL statements that alter or delete database elements, exposing data handled by the file-transfer service. Any organization running an internet-reachable MOVEit Transfer instance is affected; public internet-exposure scans around disclosure identified on the order of a few thousand servers, each typically serving enterprise or government user bases. Exploitation is confirmed in the wild: the flaw was added to CISA KEV on 2023-06-02 with known ransomware use and an EPSS exploitation probability of 99.9% (100th percentile), while no public PoC is known.

Pre-Authentication Deserialization RCE in Fortra GoAnywhere MFT
Fortra (formerly HelpSystems) GoAnywhere MFT is vulnerable to pre-authentication remote code execution (CWE-502) in the License Response Servlet, which deserializes an attacker-controlled object without validating it. An unauthenticated attacker who can reach the exposed administrative interface can send a crafted serialized object to the servlet and trigger code execution on the server. Successful exploitation gives the attacker the ability to run arbitrary code in the context of the application, which has been leveraged for ransomware operations. All organizations running GoAnywhere MFT with the affected component reachable by untrusted networks are in scope. The flaw is being actively exploited: CISA added it to the Known Exploited Vulnerabilities catalog on 2023-02-10, ransomware use is confirmed, and EPSS puts the 30-day exploitation probability at 100%.
Potential RCE in Progress Telerik UI for ASP.NET AJAX via dialog parameter tampering
Progress Telerik UI for ASP.NET AJAX before v2026.3.812 provides insufficient integrity protection (CWE-345) on the dialog request parameters used by the RadEditor file browser, allowing those parameters to be altered. To exploit it, a network attacker must first have obtained certain application encryption key material used to protect the dialog parameters, which drives the high attack complexity; no privileges or user interaction are required. With tampered parameters, the attacker can control which folders the file browser reads from, writes to, and uploads into, enabling arbitrary file uploads (CWE-434) and potentially remote code execution by writing attacker-controlled files into sensitive or web-executable locations. Any web application built with Telerik UI for ASP.NET AJAX in versions prior to 2026.3.812 is affected. Exploitation has not been observed: there is no public proof-of-concept, the flaw is not in the CISA KEV catalog, and EPSS assigns only a 0.2% probability of exploitation within 30 days.

Unauthenticated Path Traversal File Read in Telerik UI for ASP.NET AJAX RadImageEditor
Progress Telerik UI for ASP.NET AJAX versions before 2026.3.812 contain a path traversal flaw (CWE-22) in the RadImageEditor control, caused by insufficient validation of client-supplied state. A remote, unauthenticated attacker (per CVSS: AV:N/AC:L/PR:N/UI:N) can submit manipulated state so that the control's image cache returns an attacker-influenced file. Successful abuse can expose the contents of files located outside the intended image directories, producing high confidentiality impact with no integrity or availability impact per the CVSS scoring. Any web application built on Telerik UI for ASP.NET AJAX that exposes RadImageEditor on a version older than 2026.3.812 is affected. There is no known exploitation, no public proof-of-concept, the issue is not in CISA KEV, and EPSS estimates only a 0.4% chance of exploitation within 30 days.
