CVE-2021-27389 1 Siemens 2 Opcenter Quality, Qms Automotive 2026-06-17 7.5 HIGH 9.8 CRITICAL
A vulnerability has been identified in Opcenter Quality (All versions < V12.2), QMS Automotive (All versions < V12.30). A private sign key is shipped with the product without adequate protection.
CVE-2021-22644 1 Ovarro 15 Tbox Lt2-530, Tbox Lt2-530 Firmware, Tbox Lt2-532 and 12 more 2026-06-17 N/A 7.5 HIGH
Ovarro TBox TWinSoft uses the custom hardcoded user “TWinSoft” with a hardcoded key.
CVE-2020-28395 1 Siemens 16 Scalance Xr324-12m, Scalance Xr324-12m Firmware, Scalance Xr324-12m Ts and 13 more 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
A vulnerability has been identified in SCALANCE X-200RNA switch family (All versions < V3.2.7), SCALANCE X-300 switch family (incl. X408 and SIPLUS NET variants) (All versions < V4.1.0). Devices do not create a new unique private key after factory reset. An attacker could leverage this situation to a man-in-the-middle situation and decrypt previously captured traffic.
CVE-2020-28391 1 Siemens 132 Scalance X200-4pirt, Scalance X200-4pirt Firmware, Scalance X201-3pirt and 129 more 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All versions < V5.2.5), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.5.0), SCALANCE X-200RNA switch family (All versions < V3.2.7). Devices create a new unique key upon factory reset, except when used with C-PLUG. When used with C-PLUG the devices use the hardcoded private RSA-key shipped with the firmware-image. An attacker could leverage this situation to a man-in-the-middle situation and decrypt previously captured traffic.
CVE-2020-25234 1 Siemens 2 Logo\! 8 Bm, Logo\! 8 Bm Firmware 2026-06-17 3.6 LOW 7.7 HIGH
A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3), LOGO! Soft Comfort (All versions < V8.3). The LOGO! program files generated and used by the affected components offer the possibility to save user-defined functions (UDF) in a password protected way. This protection is implemented in the software that displays the information. An attacker could reverse engineer the UDFs directly from stored program files.
CVE-2020-25233 1 Siemens 2 Logo\! 8 Bm, Logo\! 8 Bm Firmware 2026-06-17 2.1 LOW 5.5 MEDIUM
A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3). The firmware update of affected devices contains the private RSA key that is used as a basis for encryption of communication with the device.
CVE-2020-25231 1 Siemens 3 Logo\! 8 Bm, Logo\! 8 Bm Firmware, Logo\! Soft Comfort 2026-06-17 2.1 LOW 5.5 MEDIUM
A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3), LOGO! Soft Comfort (All versions < V8.3). The encryption of program data for the affected devices uses a static key. An attacker could use this key to extract confidential information from protected program files.
CVE-2019-19754 2026-06-17 N/A 5.7 MEDIUM
HiveOS through 0.6-102@191212 ships with SSH host keys baked into the installation image, which allows man-in-the-middle attacks and makes identification of all public IPv4 nodes trivial with Shodan.io. NOTE: as of 2019-09-26, the vendor indicated that they would consider fixing this.
CVE-2019-19753 2026-06-17 N/A 9.1 CRITICAL
SimpleMiningOS through v1259 ships with SSH host keys baked into the installation image, which allows man-in-the-middle attacks and makes identification of all public IPv4 nodes trivial with Shodan.io. NOTE: the vendor indicated that they have no plans to fix this, and discourage deployment using public IPv4.
CVE-2019-19752 2026-06-17 N/A 9.8 CRITICAL
nvOC through 3.2 ships with SSH host keys baked into the installation image, which allows man-in-the-middle attacks and makes identification of all public IPv4 nodes trivial with Shodan.io. NOTE: as of 2019-12-01, the vendor indicated plans to fix this in the next image build.
CVE-2019-19750 1 Minerstat 1 Msos 2026-06-17 7.5 HIGH 9.8 CRITICAL
minerstat msOS before 2019-10-23 does not have a unique SSH key for each instance of the product.
CVE-2019-10920 1 Siemens 2 Logo\!8 Bm, Logo\!8 Bm Firmware 2026-06-17 5.0 MEDIUM 7.5 HIGH
A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3). Project data stored on the device, which is accessible via port 10005/tcp, can be decrypted due to a hardcoded encryption key. The security vulnerability could be exploited by an unauthenticated attacker with network access to port 10005/tcp. No user interaction is required to exploit this security vulnerability. The vulnerability impacts confidentiality of the device. At the time of advisory publication no public exploitation of this security vulnerability was known.
CVE-2018-10896 1 Canonical 1 Cloud-init 2026-06-17 3.6 LOW 7.1 HIGH
The default cloud-init configuration, in cloud-init 0.6.2 and newer, included "ssh_deletekeys: 0", disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances created by cloning a golden master or template system, sharing ssh host keys, and being able to impersonate one another or conduct man-in-the-middle attacks.
CVE-2017-7574 1 Schneider-electric 3 Modicon Tm221ce16r, Modicon Tm221ce16r Firmware, Somachine 2026-06-17 7.5 HIGH 9.8 CRITICAL
Schneider Electric SoMachine Basic 1.4 SP1 and Schneider Electric Modicon TM221CE16R 1.3.3.3 devices have a hardcoded-key vulnerability. The Project Protection feature is used to prevent unauthorized users from opening an XML protected project file, by prompting the user for a password. This XML file is AES-CBC encrypted; however, the key used for encryption (SoMachineBasicSoMachineBasicSoMa) cannot be changed. After decrypting the XML file with this key, the user password can be found in the decrypted data. After reading the user password, the project can be opened and modified with the Schneider product.
CVE-2016-4437 2 Apache, Redhat 4 Aurora, Shiro, Fuse and 1 more 2026-06-17 6.8 MEDIUM 9.8 CRITICAL
Apache Shiro before 1.2.5, when a cipher key has not been configured for the "remember me" feature, allows remote attackers to execute arbitrary code or bypass intended access restrictions via an unspecified request parameter.
CVE-2014-5419 1 Ge 14 Multilink Ml1200, Multilink Ml1200 Firmware, Multilink Ml1600 and 11 more 2026-06-17 10.0 HIGH N/A
GE Multilink ML800, ML1200, ML1600, and ML2400 switches with firmware 4.2.1 and earlier and Multilink ML810, ML3000, and ML3100 switches with firmware 5.2.0 and earlier use the same RSA private key across different customers' installations, which makes it easier for remote attackers to obtain the cleartext content of network traffic by reading this key from a firmware image and then sniffing the network.
CVE-2014-5403 1 Hospira 1 Mednet 2026-06-17 6.8 MEDIUM N/A
Hospira MedNet before 6.1 uses hardcoded cryptographic keys for protection of data transmission from infusion pumps, which allows remote attackers to obtain sensitive information by sniffing the network.
