The vulnerability stems from the use of a predictable pseudo-random number generator (PRNG) for generating a secret query name, combined with a fatal error handler that terminates the entire process.\n\n---\n## Technical Details\n\n### Vulnerability Description\n\nThe CoreDNS `loop` plugin is designed to detect forwarding loops by performing a self-test during server startup. The plugin generates a random query name (`qname`) using Go's `math/rand` package and sends an HINFO query to itself. If the server receives multiple matching queries, it assumes a forwarding loop exists and terminates.\n\n**The vulnerability arises from two design flaws:**\n\n1. **Predictable PRNG Seed**: The random number generator is seeded with `time.Now().UnixNano()`, making the generated qname predictable if an attacker knows the approximate server start time.\n\n2. **Fatal Error Handler**: When the plugin detects what it believes is a loop (3+ matching HINFO queries), it calls `log.Fatalf()` which invokes `os.Exit(1)`, immediately terminating the process without cleanup or recovery.\n\n### Affected Code\n\n**File: `plugin/loop/setup.go`**\n```go\n// PRNG seeded with predictable timestamp\nvar r = rand.New(time.Now().UnixNano())\n\n// Qname generation using two consecutive PRNG calls\nfunc qname(zone string) string {\n l1 := strconv.Itoa(r.Int())\n l2 := strconv.Itoa(r.Int())\n return dnsutil.Join(l1, l2, zone)\n}\n```\n\n**File: `plugin/loop/loop.go`**\n```go\nfunc (l *Loop) ServeDNS(ctx context.Context, w dns.ResponseWriter, r *dns.Msg) (int, error) {\n // ... validation checks ...\n \n if state.Name() == l.qname {\n l.inc() // Increment counter\n }\n\n if l.seen() > 2 {\n // FATAL: Terminates entire process\n log.Fatalf(\"Loop (%s -> %s) detected for zone %q...\", ...)\n }\n \n // ...\n}\n```\n\n**File: `plugin/pkg/log/log.go`**\n```go\nfunc Fatalf(format string, v ...any) {\n logf(fatal, format, v...)\n os.Exit(1) // Immediate process termination\n}\n```\n\n### Exploitation Window\n\nThe loop plugin remains active during the following conditions:\n\n| Condition | Window Duration | Attack Feasibility |\n|-----------|-----------------|-------------------|\n| Healthy startup | 2 seconds | Requires precise timing |\n| Self-test failure (upstream unreachable) | 30 seconds | **HIGH** - Extended window |\n| Network degradation | Variable | Depends on retry behavior |\n\n### Attack Scenario\n\n**Primary Attack Vector: Network Degradation**\n\nWhen the upstream DNS server is unreachable (network partition, misconfiguration, outage), the loop plugin's self-test fails repeatedly. During this period:\n\n1. The loop plugin remains active for up to 30 seconds\n2. Each self-test attempt generates an HINFO query visible in CoreDNS logs\n3. An attacker with log access (shared Kubernetes cluster, centralized logging) can observe the qname\n4. The attacker sends 3 HINFO queries with the observed qname\n5.

This issue has been patched in version 1.14.2.", "title": "osv - https://www.googleapis.com/download/storage/v1/b/osv-vulnerabilities/o/GIT%2FCVE-2026-26018.json?alt=media" }, { "category": "other", "text": "0.00052", "title": "EPSS" }, { "category": "other", "text": "5.4", "title": "NCSC Score" }, { "category": "other", "text": "There is news data available from source Bleepingcomputer, There is product data available from source Certbundde, VENDOR FIX as product remediation category", "title": "NCSC Score top increasing factors" }, { "category": "other", "text": "Is related to (a version of) an uncommon product, There is exploit data available from source Nvd", "title": "NCSC Score top decreasing factors" }, { "category": "details", "text": "Severity: 3\n", "title": "Vendor assessment" } ], "product_status": { "known_affected": [ "CSAFPID-5766733", "CSAFPID-5766945", "CSAFPID-5767826", "CSAFPID-1439328", "CSAFPID-1441080", "CSAFPID-2485147", "CSAFPID-2485235", "CSAFPID-2889542", "CSAFPID-2914823", "CSAFPID-5501117", "CSAFPID-1317176", "CSAFPID-5772479", "CSAFPID-5775799", "CSAFPID-5247946", "CSAFPID-5826707", "CSAFPID-3689871", "CSAFPID-3689872", "CSAFPID-3689873", "CSAFPID-3689874", "CSAFPID-3689875", "CSAFPID-3689876", "CSAFPID-3689877", "CSAFPID-3689878", "CSAFPID-3689879", "CSAFPID-3689880", "CSAFPID-3689881", "CSAFPID-3689882", "CSAFPID-3689883", "CSAFPID-3689884", "CSAFPID-3689885", "CSAFPID-3689886", "CSAFPID-3689887", "CSAFPID-3689888", "CSAFPID-3689889", "CSAFPID-3689890", "CSAFPID-3689891", "CSAFPID-3689892", "CSAFPID-3689893", "CSAFPID-3689894", "CSAFPID-3689895", "CSAFPID-3689896", "CSAFPID-3689897", "CSAFPID-3689898", "CSAFPID-3689899", "CSAFPID-3689900", "CSAFPID-3689901", "CSAFPID-3689902", "CSAFPID-3689903", "CSAFPID-3689904", "CSAFPID-3689905", "CSAFPID-3689906", "CSAFPID-3689907", "CSAFPID-3689908", "CSAFPID-3689909", "CSAFPID-3689910", "CSAFPID-3689911", "CSAFPID-3689912", "CSAFPID-3689913", "CSAFPID-3689914", "CSAFPID-3689915", "CSAFPID-3689916", "CSAFPID-3689917", "CSAFPID-3689918", "CSAFPID-3689919", "CSAFPID-3689920", "CSAFPID-3689921", "CSAFPID-3689922", "CSAFPID-3689923", "CSAFPID-3689924", "CSAFPID-3689925", "CSAFPID-3689926", "CSAFPID-3689927", "CSAFPID-3689928", "CSAFPID-3689929", "CSAFPID-3689930", "CSAFPID-3689931", "CSAFPID-3689932", "CSAFPID-3689933", "CSAFPID-3689934", "CSAFPID-3689935", "CSAFPID-3689936", "CSAFPID-3689937", "CSAFPID-3689938", "CSAFPID-3689939", "CSAFPID-3689940", "CSAFPID-3689941", "CSAFPID-3689942", "CSAFPID-5351956", "CSAFPID-5351957", "CSAFPID-5351958", "CSAFPID-5351959", "CSAFPID-5909263", "CSAFPID-5909264" ] }, "references": [ { "category": "external", "summary": "Source -
