A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

To mitigate CVE-2023-48029, organizations should implement multiple layers of defense: 1) Input Validation and Sanitization: Developers should update Corebos to sanitize or escape any user input that may be exported to CSV files, ensuring that fields starting with characters like '=', '+', '-', or '@' are neutralized or prefixed with a single quote to prevent formula execution. 2) User Awareness and Training: Administrators should be trained to recognize the risks of opening CSV files from untrusted or internal sources and to use spreadsheet software settings that disable automatic formula execution or enable 'safe mode' for CSV imports. 3) Use Alternative Export Formats: Where possible, export data in formats that do not support formula execution, such as plain text or JSON, or use CSV viewers that do not interpret formulas. 4) Restrict Low-Privilege User Input: Limit the ability of low-privileged users to input data that will be included in CSV exports, or implement review processes before data export. 5) Network and Endpoint Security: Employ endpoint protection solutions that can detect suspicious script execution and monitor for unusual administrator workstation activity. 6) Monitor for Updates: Stay alert for official patches or updates from Corebos and apply them promptly once available. 7) Implement CSV File Handling Policies: Establish organizational policies to control how exported CSV files are handled, shared, and opened, minimizing exposure to malicious payloads.

Description

Corebos 8.0 and below is vulnerable to CSV Injection. An attacker with low privileges can inject a malicious command into a table. This vulnerability is exploited when an administrator visits the user management section, exports the data to a CSV file, and then opens it, leading to the execution of the malicious payload on the administrator's computer.

Impact

For European organizations using Corebos 8.0 or earlier, this vulnerability poses a significant risk to the confidentiality and integrity of administrative systems. If exploited, attackers could execute arbitrary commands on an administrator's workstation, potentially leading to credential theft, lateral movement within the network, or deployment of malware. This could compromise sensitive customer data and business processes managed within Corebos. The attack requires low privileges to inject malicious content but relies on an administrator opening the CSV file, so social engineering or lack of user awareness could increase risk. The impact is particularly critical in sectors where Corebos is used to manage sensitive or regulated data, such as finance, healthcare, or government agencies in Europe. Additionally, the vulnerability could facilitate supply chain attacks if administrators use shared or networked devices. The absence of a patch increases exposure time, and organizations with limited security awareness or lacking CSV file handling policies are more vulnerable. Overall, this vulnerability could lead to targeted attacks against European organizations relying on Corebos, with potential data breaches and operational disruptions.
