Terra-master : Security Vulnerabilities, CVEs,

TerraMaster NAS 4.2.29 and earlier allows remote attackers to discover the administrative password by sending "User-Agent: TNAS" to module/api.php?mobile/webNasIPS and then reading the PWD field in the response.

It is possible to obtain the first administrator's hash set up in Terramaster F4-210, F2-210 TOS 4.2.X (4.2.15-2107141517) on the system as well as other information such as MAC address, internal IP address etc. by performing a request to the /module/api.php?mobile/wapNasIPS endpoint.

In Terramaster F4-210, F2-210 TOS 4.2.X (4.2.15-2107141517), an attacker can self-sign session cookies by knowing the target's MAC address and the user's password hash. Guest users (disabled by default) can be abused using a null/empty hash and allow an unauthenticated attacker to login as guest.

It is possible to execute arbitrary commands as root in Terramaster F4-210, F2-210 TOS 4.2.X (4.2.15-2107141517) by sending specifically crafted input to /tos/index.php?app/app_start_stop.

It is possible to obtain the first administrator's hash set up on the system in Terramaster F4-210, F2-210 TOS 4.2.X (4.2.15-2107141517) as well as other information such as MAC address, internal IP address etc. by performing a request to the /module/api.php?mobile/webNasIPS endpoint.

It is possible to execute arbitrary commands as root in Terramaster F4-210, F2-210 TOS 4.2.X (4.2.15-2107141517) by sending a specifically crafted input to /tos/index.php?app/del.

An authenticated attacker can execute arbitrary commands as root in Terramaster F4-210, F2-210 TOS 4.2.X (4.2.15-2107141517) by injecting a maliciously crafted input in the request through /tos/index.php?app/hand_app.

TerraMaster F2-210 devices through 2021-04-03 use UPnP to make the admin web server accessible over the Internet on TCP port 8181, which is arguably inconsistent with the "It is only available on the local network" documentation. NOTE: manually editing /etc/upnp.json provides a partial but undocumented workaround.

An unauthenticated command-execution vulnerability exists in TerraMaster TOS through 4.2.06 via shell metacharacters in the Event parameter in include/makecvs.php during CSV creation.

Incorrect Access Control vulnerability in TerraMaster TOS <= 4.2.06 allows remote authenticated attackers to bypass read-only restriction and obtain full access to any folder within the NAS

TerraMaster TOS <= 4.2.06 was found to check for updates (of both system and applications) via an insecure channel (HTTP). Man-in-the-middle attackers are able to intercept these requests and serve a weaponized/infected version of applications or updates.

Remote Command Execution (RCE) vulnerability in TerraMaster TOS <= 4.2.06 allow remote unauthenticated attackers to inject OS commands via /include/makecvs.php in Event parameter.

Multiple directory traversal vulnerabilities in TerraMaster TOS <= 4.2.06 allow remote authenticated attackers to read, edit or delete any file within the filesystem via the (1) filename parameter to /tos/index.php?editor/fileGet, Event parameter to /include/ajax/logtable.php, or opt parameter to /include/core/index.php.

Email Injection in TerraMaster TOS <= 4.2.06 allows remote unauthenticated attackers to abuse the forget password functionality and achieve account takeover.

User Enumeration vulnerability in TerraMaster TOS <= 4.2.06 allows remote unauthenticated attackers to identify valid users within the system via the username parameter to wizard/initialise.php.

Cross-site scripting (XSS) vulnerability in TerraMaster TOS <= 4.2.06 allows remote authenticated users to inject arbitrary web script or HTML via the mod parameter to /module/index.php.

TerraMaster TOS before 4.1.29 has Invalid Parameter Checking that leads to code injection as root. This is a dynamic class method invocation vulnerability in include/exportUser.php, in which an attacker can trigger a call to the exec method with (for example) OS commands in the opt parameter.

An issue was discovered on TerraMaster FS-210 4.0.19 devices. An unauthenticated attacker can download log files via the include/makecvs.php?Event= substring.

An issue was discovered on TerraMaster FS-210 4.0.19 devices. An authenticated remote non-administrative user can read unauthorized shared files, as demonstrated by the filename=*public*%25252Fadmin_OnlyRead.txt substring.

An issue was discovered on TerraMaster FS-210 4.0.19 devices. One can download backup files remotely from terramaster_TNAS-00E43A_config_backup.bin without permission.

An issue was discovered on TerraMaster FS-210 4.0.19 devices. Normal users can use 1.user.php for privilege elevation.

System command injection in ajaxdata.php in TerraMaster TOS 3.1.03 allows attackers to execute system commands via the "newname" parameter.

User enumeration in usertable.php in TerraMaster TOS version 3.1.03 allows attackers to list all system users via the "modgroup" parameter.

Cross-site scripting in Text Editor in TerraMaster TOS version 3.1.03 allows attackers to execute JavaScript via the "filename" URL parameter.

Cross-site scripting in usertable.php in TerraMaster TOS version 3.1.03 allows attackers to execute JavaScript via the "modgroup" parameter.
