Description

all the Toshiba printers have programs containing a hardcoded key used to encrypt files. An attacker can decrypt the encrypted files using the hardcoded key. Insecure algorithm is used for the encryption. This vulnerability can be executed in combination with other vulnerabilities and difficult to execute alone. So, the CVSS score for this vulnerability alone is lower than the score listed in the Base Score of this vulnerability. For detail on related other vulnerabilities, please ask to the below contact point. https:www.toshibatec.comcontactsproducts As for the affected productsmodelsversions, see the reference URL.

Can you explain the CVE description?

This CVE description is about a vulnerability identified as CVE-2024-27161, which affects all Toshiba printers. The vulnerability exists in the hardcoded key used to encrypt files in the printer programs. An attacker can decrypt the encrypted files using this hardcoded key because an insecure algorithm is used for encryption. The vulnerability is rated with a CVSS score of 6.2, which is considered medium severity. However, the description notes that this vulnerability is difficult to execute alone and may require combination with other vulnerabilities to be exploited effectively. As a result, the CVSS score for this vulnerability alone is lower than the base score listed. The status of this vulnerability is EARLY_WARNING, and it was published on June 14, 2024. The CWE associated with this vulnerability is CWE-798. The affected products, models, and versions are listed in the reference URLs provided. For more details on related vulnerabilities, the contact point is given as the Toshiba website. Additional resources related to this CVE can be found in the provided URLs. The vector CVSS shows the attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact. Overall, this vulnerability highlights a security issue in Toshiba printers that could potentially lead to unauthorized access to encrypted files.

How can this vulnerability be part of an attack tree?

This vulnerability can be part of an attack tree by being leveraged in combination with other vulnerabilities to escalate the impact of an attack. For example, an attacker could exploit this hardcoded key vulnerability to decrypt sensitive files on Toshiba printers, and then use the decrypted information to launch further attacks on the network or steal valuable data. By combining this vulnerability with others, such as a privilege escalation vulnerability or a remote code execution vulnerability, the attacker can achieve a more significant impact than by exploiting this vulnerability alone. This highlights the importance of addressing and mitigating all vulnerabilities in a system to prevent them from being used as stepping stones in a larger attack.
