This flaw stems from improper neutralization of special elements used in an OS command, commonly known as shell command injection. A remote authenticated attacker can exploit this vulnerability to execute arbitrary code on the underlying server. This means that if an attacker obtains valid credentials for a Faspex 5 instance, they can leverage this vulnerability to gain full control over the system hosting the application. The widespread use of Aspera Faspex for high-speed, secure file transfer makes this a significant concern for organizations relying on the product for critical business operations and data exchange. The vulnerability poses a severe risk to the confidentiality, integrity, and availability of affected systems and data.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker obtains valid user credentials for an IBM Aspera Faspex 5 application instance.\u003c/li\u003e\n\u003cli\u003eThe attacker uses these credentials to successfully authenticate to the IBM Aspera Faspex 5 web interface.\u003c/li\u003e\n\u003cli\u003eThe attacker identifies a specific input field within the authenticated application context that processes user-supplied data as part of an underlying shell command.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious string that includes operating system commands, utilizing shell metacharacters such as semicolons (\u003ccode\u003e;\u003c/code\u003e), pipes (\u003ccode\u003e|\u003c/code\u003e), or double ampersands (\u003ccode\u003e\u0026amp;\u0026amp;\u003c/code\u003e).\u003c/li\u003e\n\u003cli\u003eThis malicious string is then injected into the vulnerable input field in the Faspex 5 application.\u003c/li\u003e\n\u003cli\u003eUpon processing this input, the IBM Aspera Faspex 5 application executes the embedded malicious OS command, alongside or instead of the intended command.\u003c/li\u003e\n\u003cli\u003eThis execution grants the attacker arbitrary code execution capabilities on the server hosting Faspex 5, allowing for various malicious activities.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-14959 by a remote authenticated attacker grants arbitrary code execution capabilities on the underlying server. This can lead to complete compromise of the affected IBM Aspera Faspex 5 system. The impact includes unauthorized access to sensitive data, modification or deletion of critical files, establishment of persistent backdoors, and the potential for lateral movement within the network. Organizations using Faspex 5 for transferring large or sensitive files could face severe data breaches, disruption of file transfer services, and significant operational downtime, potentially leading to financial losses and reputational damage.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePatch CVE-2026-14959 immediately by upgrading IBM Aspera Faspex 5 to a patched version beyond 5.0.15.4, as detailed in the IBM Corporation reference.\u003c/li\u003e\n\u003cli\u003eImplement strong authentication policies, including multi-factor authentication, to prevent unauthorized access that could lead to exploitation of vulnerabilities like CVE-2026-14959.\u003c/li\u003e\n\u003cli\u003eReview access logs and process execution logs for IBM Aspera Faspex 5 servers for unusual command line arguments or processes indicative of post-authentication exploitation attempts.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-07-28T21:21:34Z","date_published":"2026-07-28T21:21:34Z","id":"https://feed.craftedsignal.io/briefs/2026-07-cve-2026-14959-ibm-aspera-faspex-rce/","summary":"A critical vulnerability, CVE-2026-14959, in IBM Aspera Faspex 5 (versions 5.0.0 through 5.0.15.4) allows a remote authenticated attacker to execute arbitrary code due to a shell command injection flaw, potentially leading to full system compromise and significant data loss or service disruption.","title":"CVE-2026-14959: IBM Aspera Faspex 5 Remote Code Execution via Shell Command Injection","url":"https://feed.craftedsignal.io/briefs/2026-07-cve-2026-14959-ibm-aspera-faspex-rce/"}],"language":"en","title":"CraftedSignal Threat Feed - Aspera Faspex 5","version":"https://jsonfeed.org/version/1.1"}
