This vulnerability allows a malicious actor with access to add or modify content in an instance of the Backstage software catalog to inject script URLs in the entities stored in the catalog. If users of the catalog then click on said URLs, that can lead to an XSS attack.\n\nThis vulnerability has been patched in both the frontend and backend implementations. The default `Link` component from `@backstage\u002Fcore-components` version 1.2.0 and greater will now reject `javascript:` URLs, and there is a global override of `window.open` to do the same. In addition, the catalog model v0.12.4 and greater as well as the catalog backend v1.7.2 and greater now has additional validation built in that prevents `javascript:` URLs in known annotations. As a workaround, the general practice of limiting access to modifying catalog content and requiring code reviews greatly help mitigate this vulnerability.","Backstage is an open platform for building developer portals. `@backstage\u002Fcatalog-model` prior to version 1.2.0, `@backstage\u002Fcore-components` prior to 0.12.4...","2023-02-14T18:15:13.577","2023-11-07T04:09:01.073",5.4,"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:L\u002FUI:R\u002FS:C\u002FC:L\u002FI:L\u002FA:N",{"CVSSMetricV31":15,"CVSSMetricV30":27,"CVSSMetricV2":27,"CVSSMetricV40":27},[16,30],{"Source":17,"Type":18,"CVSSData":19,"ExploitabilityScore":28,"ImpactScore":29},"nvd@nist.gov","Primary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":22,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":22,"IntegrityImpact":22,"AvailabilityImpact":25,"BaseScore":12,"BaseSeverity":26,"ExploitCodeMaturity":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"TemporalSeverity":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":25,"ModifiedAttackVector":27,"ModifiedAttackComplexity":27,"ModifiedPrivilegesRequired":27,"ModifiedUserInteraction":27,"ModifiedScope":27,"ModifiedConfidentialityImpact":27,"ModifiedIntegrityImpact":27,"ModifiedAvailabilityImpact":27,"EnvironmentalScore":27,"EnvironmentalSeverity":27},"3.1","NETWORK","LOW","REQUIRED","CHANGED","NONE","MEDIUM",null,2.3,2.7,{"Source":31,"Type":32,"CVSSData":33,"ExploitabilityScore":28,"ImpactScore":37},"a0819718-46f1-4df5-94e2-005712e83aaa","Secondary",{"Version":20,"VectorString":34,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":22,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":35,"IntegrityImpact":25,"AvailabilityImpact":25,"BaseScore":36,"BaseSeverity":26,"ExploitCodeMaturity":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"TemporalSeverity":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":25,"ModifiedAttackVector":27,"ModifiedAttackComplexity":27,"ModifiedPrivilegesRequired":27,"ModifiedUserInteraction":27,"ModifiedScope":27,"ModifiedConfidentialityImpact":27,"ModifiedIntegrityImpact":27,"ModifiedAvailabilityImpact":27,"EnvironmentalScore":27,"EnvironmentalSeverity":27},"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:L\u002FUI:R\u002FS:C\u002FC:H\u002FI:N\u002FA:N","HIGH",6.8,4,0.00453,[38,38,38,38,38,38,38],"Medium",[42,47,50],{"vendor":43,"product":44,"version":45,"criteria":46,"vulnerable":4},"linuxfoundation","backstage_catalog-model","*","cpe:2.3:a:linuxfoundation:backstage_catalog-model:*:*:*:*:*:node.js:*:*",{"vendor":43,"product":48,"version":45,"criteria":49,"vulnerable":4},"backstage_core-components","cpe:2.3:a:linuxfoundation:backstage_core-components:*:*:*:*:*:node.js:*:*",{"vendor":43,"product":51,"version":45,"criteria":52,"vulnerable":4},"backstage_plugin-catalog-backend","cpe:2.3:a:linuxfoundation:backstage_plugin-catalog-backend:*:*:*:*:*:node.js:*:*",3,[55,60],{"url":56,"source":57,"tags":58},"https:\u002F\u002Fgithub.com\u002Fbackstage\u002Fbackstage\u002Fcommit\u002F3d1371954512f7fa8bd0e2d357e00eada2c3e8a8","GitHub",[59],"Patch",{"url":61,"source":57,"tags":62},"https:\u002F\u002Fgithub.com\u002Fbackstage\u002Fbackstage\u002Fsecurity\u002Fadvisories\u002FGHSA-7hv8-3fr9-j2hv",[63],"Vendor Advisory",2,[66,74],{"id":67,"name":68,"description":69,"extendedDescription":70,"status":71,"abstraction":72,"structure":73},"CWE-79","Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.","Cross-site scripting (XSS) vulnerabilities occur when:\nThere are three main kinds of XSS:\nOnce the malicious script is injected, the attacker can perform a variety of malicious activities. The attacker could transfer private information, such as cookies that may include session information, from the victim's machine to the attacker. The attacker could send malicious requests to a web site on behalf of the victim, which could be especially dangerous to the site if the victim has administrator privileges to manage that site. Phishing attacks could be used to emulate trusted web sites and trick the victim into entering a password, allowing the attacker to compromise the victim's account on that web site. Finally, the script could exploit a vulnerability in the web browser itself possibly taking over the victim's machine, sometimes referred to as \"drive-by hacking.\"\nIn many cases, the attack can be launched without the victim even being aware of it. Even with careful users, attackers frequently use a variety of methods to encode the malicious portion of the attack, such as URL encoding or Unicode, so the request looks less suspicious.","Stable","Base","Simple",{"id":75,"name":76,"description":77,"extendedDescription":78,"status":79,"abstraction":80,"structure":73},"CWE-84","Improper Neutralization of Encoded URI Schemes in a Web Page","The web application improperly neutralizes user-controlled input for executable script disguised with URI encodings.","","Draft","Variant",false,[],{"title":84,"metaDescription":85,"keywords":86,"canonicalUrl":87,"structuredData":88},"What is CVE-2023-25571?
