Wso2 Api Control Plane
Monthly
OS command injection (CWE-78) in WSO2's shared Carbon Console administrative interface allows an authenticated administrator with adjacent network access to execute arbitrary operating system commands, leading to complete compromise of the affected system. The vulnerability spans at least eight WSO2 middleware products - including API Manager, Identity Server, Open Banking components, Traffic Manager, Universal Gateway, and API Control Plane - all of which share the Carbon Console administrative layer. The CVSS scope-change flag (S:C) indicates that successful exploitation extends impact beyond the WSO2 application boundary to the underlying host and potentially adjacent systems.
WSO2 API Manager and API Control Plane use a non-cryptographic PRNG in the API Publisher component to generate shared secrets for Webhook HMAC validation, violating the principle that secret generation must use cryptographically secure entropy sources (CWE-330). An unauthenticated remote attacker who can observe sufficient PRNG-derived webhook secrets - for example via API Publisher UI or intercepted webhook registrations - can statistically reconstruct the generator state and predict future secrets. With a predicted secret, the attacker forges event payloads bearing valid HMAC signatures, bypassing the API Gateway's authenticity checks and enabling unauthorized event injection, data manipulation, and potential downstream system compromise. No public exploit or CISA KEV listing has been identified at time of analysis.
Authentication bypass in WSO2 API Manager and related components (Universal Gateway, Traffic Manager, API Control Plane, and the Carbon API Manager REST API Utility) allows remote unauthenticated attackers to forge JWT tokens because the authentication layer accepts tokens signed with algorithms outside the explicitly configured/supported set. By crafting a JWT with an unsupported or attacker-chosen algorithm that is then incorrectly validated, an attacker can gain unauthorized access up to full administrative account takeover. Rated CVSS 10.0 (scope-changed) by WSO2, with the description noting a contained 9.8 score for single-tenant deployments; no public exploit identified at time of analysis.
Privilege escalation in WSO2 API Manager and related Carbon-based products allows a low-privileged user, using a validly issued token, to invoke product-level Admin REST APIs that should be restricted, potentially resulting in full administrative account takeover. The flaw stems from insufficient scope/privilege restriction on issued tokens (CWE-269) and affects API Manager, API Control Plane, Universal Gateway, Traffic Manager, and the Carbon REST API common/utility components. No public exploit identified at time of analysis; exploitation requires the attacker to already hold a low-privileged account and obtain a token for it.
Authentication bypass in WSO2 Identity Server and multiple WSO2 platform products (API Manager, Open Banking AM/IAM/KM, Traffic Manager, Universal Gateway, API Control Plane, Identity Server as Key Manager) lets an attacker skip intermediate multi-factor challenges when the Conditional (Adaptive) Authentication script is configured with a particular multi-step callback/re-execution pattern, resulting in unauthorized takeover of a targeted user account. The flaw stems from the adaptive script failing to enforce completion of all required steps, and carries a high CVSS of 9.4 (C:H/I:H). There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the affected components underpin enterprise SSO/MFA and open-banking IAM, making impact severe where the vulnerable flow exists.
Sensitive information disclosure in WSO2's Carbon Event Publisher Core affects nine WSO2 platform products, including API Manager, Identity Server, and Open Banking components. When an Event Publisher output adapter is misconfigured with extraneous or irrelevant properties, those property values - which may include user credentials or confidential data - are written to the wso2carbon log files without sanitization or masking (CWE-532). A local, high-privileged actor with read access to those log files can extract the inadvertently logged secrets and leverage them for unauthorized access. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
CSRF in the WSO2 Carbon console Ajax processor enables an attacker to silently execute unauthorized state-changing operations on behalf of authenticated administrators across more than ten WSO2 products including Identity Server, API Manager, and Enterprise Integrator. The vulnerability combines two compounding weaknesses: state-altering operations are routed over HTTP GET, and the sole CSRF mitigation - SameSite=Lax - is defeated because browsers permit session cookies to accompany cross-origin top-level GET navigations. No public exploit code has been reported and this CVE does not appear in CISA KEV at time of analysis; however, the breadth of affected WSO2 products and the IAM/API management context make misconfigured internet-exposed deployments a meaningful target for targeted social engineering.
Persistent denial of service in multiple WSO2 products - including WSO2 API Manager, WSO2 Universal Gateway, WSO2 Traffic Manager, and WSO2 API Control Plane - allows an unauthenticated remote attacker to send malicious JSON payloads to the throttling event handling mechanism, crashing or corrupting API Gateway state so that legitimate API traffic can no longer be processed. Because the outage is persistent and requires manual intervention to restore service, and the CVSS scope is changed (S:C), a single request can take down the entire API Gateway tier. There is no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.
Reflected cross-site scripting across at least eight WSO2 platform products - including Identity Server, API Manager, API Control Plane, Traffic Manager, Universal Gateway, Open Banking AM/IAM, and Identity Server as Key Manager - allows unauthenticated remote attackers to inject arbitrary script via unsanitized URL parameters. An attacker who tricks an authenticated user into clicking a crafted link can redirect the victim to a malicious site, tamper with rendered page content, or exfiltrate non-session browser data; partial mitigation is provided by httpOnly flags on session cookies, which block direct session token theft. No public exploit identified at time of analysis; WSO2 self-reported the issue and published advisory WSO2-2025-4343.
Role-based access control bypass in WSO2 API Manager 3.x allows authenticated users with the 'Internal/Everyone' role to invoke Gateway and Internal Service APIs without proper permission enforcement, enabling unauthorized operations on sensitive REST API endpoints. The vulnerability affects multiple WSO2 products including API Control Plane, Universal Gateway, and Traffic Manager. CVSS 6.3 (network-accessible, low complexity, requires valid user credentials) indicates moderate severity with clear lateral privilege escalation potential in multi-tenant environments.
HTTP response header injection in WSO2 Webhook API invocations allows unauthenticated remote attackers to inject or overwrite arbitrary HTTP response headers via unsanitized user-supplied input. Successful exploitation enables cache manipulation, security header alteration, cookie injection, and potential session hijacking. CVSS 5.3 (network-accessible, low complexity, no authentication required); no public exploit code or active exploitation confirmed at time of analysis.
