Occasionally an issue is determined to be a design or coding flaw with implications that may impact product cyber security.\n\nWhen a potential product vulnerability is identified or reported, ABB immediately initiates our vulnerability handling process. This entails validating if the issue is in fact a product issue, identifying root causes, determining what related products may be impacted, developing a remediation, and notifying end users and governmental organizations.\n\nThe resulting Cyber Security Advisory intends to notify customers of the vulnerability and provide details on which products are impacted, how to mitigate the vulnerability or explain workarounds that minimize the potential risk as much as possible. The release of a Cyber Security Advisory should not be misconstrued as an affirmation or indication of an active threat or ongoing campaign targeting the products mentioned here. If ABB is aware of any specific threats, it will be clearly mentioned in the communication.\n\nThe publication of this Cyber Security Advisory is an example of ABB\u2019s commitment to the user community in support of this critical topic. Responsible disclosure is an important element in the chain of trust we work to maintain with our many customers. The release of an Advisory provides timely information which is essential to help ensure our customers are fully informed.", "title": "Purpose" }, { "category": "faq", "text": "What causes the vulnerability?\n- A flaw was found in the Linux kernel's algif_aead cryptographic algorithm interface. An incorrect 'in-place operation' was introduced, where the source and destination data mappings were different. This could lead to unexpected behavior or data integrity issues during cryptographic operations, potentially impacting the reliability of encrypted communications. \n\nWhat is Edgenius?\n- ABB Ability\u2122 Edgenius is an edge computing platform that\n - Connects to control systems, devices, and equipment\n - Collects and contextualizes operational data\n - Hosts applications that deliver real-time insights and AI-driven recommendations\n\nWhat might an attacker use the vulnerability to do?\n- Successful exploitation could enable a local user attacker to gain administrative control of the system node, execute arbitrary code, or cause the node to become unavailable.\n\nHow could an attacker exploit the vulnerability?\n- An attacker could exploit this vulnerability after obtaining local access to the system. By invoking the Linux kernel\u2019s affected cryptographic interface (algif_aead), the attacker can trigger incorrect memory handling in the kernel. This allows the attacker to escalate privileges from a normal user to full administrative (root) access on the affected system node\n\nCould the vulnerability be exploited remotely? \n- No, to exploit this vulnerability an attacker would need to have local access (physical access or through valid SSH credentials) to an affected system node.\n\nWhat does the update do?\n- The update resolves the issue by incorporating the security update of the Linux kernel. \n\nWhen this security advisory was issued, had this vulnerability been publicly disclosed?\n- Yes, this vulnerability has been publicly disclosed.\n\nWhen this security advisory was issued, had ABB received any reports that this vulnerability was being exploited?\n- No, ABB had not received any information indicating that this vulnerability had been exploited for Edgenius when this security advisory was originally issued.\n", "title": "Frequently Asked Questions" }, { "category": "legal_disclaimer", "text": "This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy).", "title": "Legal Notice and Terms of Use" }, { "category": "other", "text": "This ICSA is a verbatim republication of ABB PSIRT 7PAA024620 from a direct conversion of the vendor's Common Security Advisory Framework (CSAF) advisory.
