Omada Er605 Firmware

A cryptographic weakness exists in affected Omada devices where site credentials are protected using a legacy hashing algorithm that does not provide sufficient protection. An attacker who obtains access to stored credential data may be able to recover valid credentials to gain unauthorized access to affected devices or management environments.Show less

A race condition exists in the cloud-based Omada device adoption process when an attacker may be able to interact with the adoption workflow before a legitimate device completes registration, resulting in provisioning information being delivered to an attacker. Successful exploitation may allow disclosure of provisioning information intended for a legitimate device.Show less

A cryptographic weakness exists in the Omada adoption protocol where session encryption keys used to protect communications between controllers and managed devices may be predictable due to insufficient entropy in session key generation. An attacker who successfully intercepts adoption-related communications may be able to recover session encryption keys and decrypt affected communications.Show less

Affected Omada devices rely on embedded certificates that are shared across deployments to establish trust between controllers and managed devices. An attacker who obtains the embedded certificates may be able to impersonate trusted controllers or devices and intercept affected communications.Show less

A cryptographic weakness exists in the Omada adoption protocol.  The protocol relies on hard-coded cryptographic keys to establish trust and protect authentication exchanges between controllers and managed devices during device adoption. An attacker may be able to impersonate trusted controllers or managed devices and gain access to sensitive adoption-related communications.Show less

A cryptographic weakness exists in the Omada device adoption process.  During adoption, authentication credentials associated with site management are transmitted using a weak hashing algorithm that does not provide sufficient protection. An attacker who successfully intercepts adoption-related authentication traffic may be able to recover valid credentials and gain unauthorized access to managed devices or controller-managed environments.Show less

A certification validation weakness exists in communication between affected Omada devices and cloud controllers. Certificate identity verification does not adequately validate that a presented certificate corresponds to the expected cloud controller hostname, which may allow certificate validation protections to be bypassed under specific conditions. Successful exploitation may allow interception or modification of communication between affected devices and cloud controllers.Show less

TP-Link Omada ER605 Reliance on Security Through Obscurity Vulnerability. This vulnerability allows network-adjacent attackers to access or spoof DDNS messages on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are vulnerable only if configured to use the Comexe DDNS service. The specific flaw exists within the cmxddnsd executable. The issue results from reliance on obscurity to secure network data. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-22439.Show less

TP-Link Omada ER605 Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are vulnerable only if configured to use the Comexe DDNS service. The specific flaw exists within the handling of DNS names. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22523.Show less

TP-Link Omada ER605 Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are vulnerable only if configured to use the Comexe DDNS service. The specific flaw exists within the handling of DDNS error codes. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22522.Show less

TP-Link Omada ER605 Comexe DDNS Response Handling Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are vulnerable only if configured to use the Comexe DDNS service. The specific flaw exists within the handling of DNS responses. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22383.Show less

TP-Link Omada ER605 PPTP VPN username Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are only vulnerable if configured to use a PPTP VPN with LDAP authentication. The specific flaw exists within the handling of the username parameter provided to the /usr/bin/pppd endpoint. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22446.Show less

TP-Link Omada ER605 Access Control Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605. Authentication is required to exploit this vulnerability. The specific issue exists within the handling of the name field in the access control user interface. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22227.Show less

TP-Link Omada ER605 DHCPv6 Client Options Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DHCP options. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22420.Show less

In TP-Link Omada er605 1.0.1 through (v2.6) 2.2.3, a cloud-brd binary is susceptible to an integer overflow that leads to a heap-based buffer overflow. After heap shaping, an attacker can achieve code execution in the context of the cloud-brd binary that runs at the root level. This is fixed in ER605(UN)_v2_2.2.4 Build 020240119.Show less
