Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical security flaw in `xwiki-pro-macros` allows Remote Code Execution (RCE). π **Consequences**: Attackers can fully compromise the server, leading to total data loss and system takeover.β¦
π‘οΈ **Root Cause**: CWE-95 (Improper Neutralization of Special Elements in Code). π **Flaw**: The `width` parameter is **not escaped** properly.β¦
π¦ **Affected**: `xwiki-pro-macros` by XWiki SAS. π **Versions**: All versions **before 1.26.5** are vulnerable. If you are running 1.26.4 or lower, you are at risk! β οΈ
Q4What can hackers do? (Privileges/Data)
π» **Privileges**: Full Remote Code Execution (RCE). π΅οΈ **Data**: Complete compromise of Confidentiality, Integrity, and Availability (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). Hackers get full control! π
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. π **Auth**: No authentication required (PR:N). π±οΈ **UI**: No user interaction needed (UI:N). π **Access**: Network accessible (AV:N). This is an easy target for automated bots! π€
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exploit**: No public PoC or exploit code is currently listed in the data. π **Status**: While no wild exploit exists yet, the low barrier to entry makes it highly likely to be weaponized soon. Stay alert! π
Q7How to self-check? (Features/Scanning)
π **Check**: Scan your XWiki instances for `xwiki-pro-macros` components. π **Version**: Verify if the version is < 1.26.5. π οΈ **Tool**: Use vulnerability scanners that check for CWE-95 in macro parameters.β¦
π₯ **Urgency**: **CRITICAL**. π¨ **Priority**: Patch **IMMEDIATELY**. With CVSS High severity and no auth required, the risk of exploitation is imminent. Do not delay! β°
