CVE-2025-54196 is an Open Redirect vulnerability (CWE-601) affecting Adobe Connect versions 12.9 and earlier. This vulnerability allows an attacker to craft URLs that appear to originate from a legitimate Adobe Connect domain but redirect users to untrusted, potentially malicious websites. The attack vector requires no privileges and no authentication but does require user interaction, specifically that the victim clicks on a maliciously crafted link. The vulnerability does not directly compromise confidentiality or availability but can be used as part of phishing or social engineering campaigns to trick users into visiting malicious sites, potentially leading to credential theft or malware infection. The CVSS 3.1 base score is 3.1 (low), reflecting the limited technical impact and the requirement for user interaction. No patches or exploits are currently reported, but organizations using Adobe Connect should be aware of the risk. The vulnerability arises from insufficient validation of redirect URLs within the Adobe Connect application, allowing attackers to manipulate redirect parameters to point to external domains. This can undermine user trust and facilitate further attacks if combined with other vulnerabilities or social engineering tactics.

For European organizations, the primary impact is the increased risk of phishing and social engineering attacks leveraging trusted Adobe Connect URLs to redirect users to malicious sites. This can lead to credential compromise, malware infections, or unauthorized access if users are deceived. Organizations heavily reliant on Adobe Connect for remote collaboration and virtual meetings may see increased targeting. While the vulnerability itself does not allow direct system compromise, it lowers the barrier for attackers to conduct successful phishing campaigns. This can be particularly impactful in sectors with high remote work adoption, such as finance, government, and education. The reputational damage and potential data breaches resulting from successful phishing attacks could have regulatory and financial consequences under GDPR and other European data protection laws.

1. Educate users to be cautious about clicking on links, especially those received via email or chat, even if they appear to come from trusted Adobe Connect domains. 2. Implement URL filtering and validation on the server side to restrict redirect URLs to trusted domains only, preventing arbitrary external redirects. 3. Monitor logs for unusual redirect patterns or spikes in redirected traffic to unknown domains. 4. Apply patches or updates from Adobe promptly once available to address this vulnerability. 5. Use multi-factor authentication (MFA) to reduce the impact of credential theft resulting from phishing. 6. Employ email security solutions with phishing detection and URL rewriting to warn users about potentially malicious links. 7. Consider deploying web proxies or secure web gateways that can block access to known malicious domains. 8. Review and harden Adobe Connect configurations to minimize exposure to open redirect parameters.
